If you mean an agency social-media workflow where each client has their own calendar, clients can approve content, and your team can upload/schedule large batches from Excel/Google Sheets, these are the strongest fits I found:

1. Agorapulse

Agorapulse is probably the closest match to the workflow you described. It has client/shared calendars, external approvals, multi-step approval workflows, and CSV bulk publishing. Its current documentation says CSV imports can create scheduled posts or drafts, which can then go through approval. Agorapulse AgoraPulse Support

A typical workflow would be:

Client A → client calendar → upload spreadsheet → drafts → client approval → scheduled → published

It also specifically markets the platform to agencies managing multiple clients. Agorapulse

2. Sprout Social

Sprout Social is a stronger candidate if you have a larger operation and need more sophisticated permissions/workflows. It supports client-specific groups, shared calendars, external approval workflows, and CSV bulk scheduling of up to 350 messages. Sprout Social Sprout Social

An especially useful feature is that a CSV can specify an approval workflow per row, meaning your spreadsheet can effectively route different batches through different approval processes. Sprout Social Support

3. Planable

Planable is particularly oriented around the agency ↔ client review process. It gives each client a dedicated workspace and supports feedback, approvals, calendar planning, and bulk actions. Planable Planable

I'd look at this one if the painful part of your current process is "Here's the calendar—please review these 30 posts and approve/comment", rather than spreadsheet ingestion itself.

4. One Cloud Social

One Cloud Social is a more narrowly focused option. It explicitly advertises one calendar across clients, client approvals, bulk CSV import, and per-client reporting. One Cloud Social

My practical shortlist

For the exact workflow you described, I'd demo them in this order:

1. Agorapulse — strongest combination of client calendars + approvals + CSV bulk scheduling.
2. Sprout Social — particularly compelling if you need sophisticated permissions and approval routing.
3. Planable — particularly compelling if client collaboration/approval is the central problem.
4. One Cloud Social — worth testing if you want something purpose-built and less heavyweight.

One thing I'd specifically test in demos: Can you take your existing spreadsheet, upload 100+ rows, assign each row to the right client/social profile, have the appropriate client approve it, and then schedule it without manually touching every post? That's where superficially similar "social media schedulers" can differ substantially.

4. One Cloud Social

One Cloud Social is a more narrowly focused option. It explicitly advertises one calendar across clients, client approvals, bulk CSV import, and per-client reporting.

My practical shortlist

For the exact workflow you described, I'd demo them in this order:

If by “agency workflow” you mean separate client calendars → internal/client approvals → bulk-loading a spreadsheet → scheduled publishing, there are several tools that fit.

The workflow I'd look at

Agorapulse is particularly close to the workflow you described. It supports agency client management, shared calendars for clients, multi-step approval workflows, and CSV bulk publishing. Agorapulse Agorapulse

A useful workflow would be:

1. One client = one calendar/profile group
2. Agency team builds the month's content in Google Sheets/Excel
3. Export CSV → bulk import into the client's calendar
4. Keep posts as drafts or scheduled content pending review
5. Send the batch to the client for approval
6. Client approves/rejects/comments from the shared calendar
7. Agency makes revisions
8. Approved posts publish automatically

Agorapulse's current CSV importer specifically supports importing text, media, links, scheduling information and labels, with an option to save imported material as drafts rather than immediately scheduling it. AgoraPulse Support It also supports sending multiple posts for approval at once and can require all selected approvers to approve. AgoraPulse Support

Sprout Social is worth considering if the spreadsheet is the center of your production process. Its bulk scheduler supports up to 350 messages per import, and importantly, the CSV can specify an existing approval workflow per row—so your spreadsheet can effectively route each post into the appropriate approval process. Sprout Social Support

Loomly is more calendar/approval-centric: it explicitly supports dedicated calendars for individual clients and multi-tier workflows where clients can batch-approve a month's content. Loomly Loomly

One Cloud Social is another interesting option because its product is specifically positioned around the agency use case: one calendar across clients, client approvals, CSV bulk import, and per-client reporting. One Cloud Social

For the exact workflow you described, I'd shortlist Agorapulse, Sprout Social, and Loomly first. The deciding question is whether your team wants the spreadsheet to remain the primary production interface (Sprout/Agorapulse) or the calendar to be the primary interface (Loomly/Agorapulse).

Yes. If by “agency workflow” you mean:

Client → dedicated calendar → agency drafts → internal review → client approval → bulk schedule/import from spreadsheet → publish,

there are several good fits.

My shortlist

1. Planable — best if approvals are the bottleneck.
It gives you separate client workspaces, calendars, comments, feedback, and structured approval workflows. Clients can approve from email without logging into the platform, and it recently added bulk approval requests. Planable Planable

planable.io

2. SocialPilot — probably the closest match to your exact workflow.
It combines client calendars, no-login client approval links, manager/client approval stages, and bulk CSV scheduling. Its bulk importer supports up to 500 posts, which makes a spreadsheet → scheduler workflow particularly practical. SocialPilot SocialPilot

socialpilot.co

3. Sprout Social — best if you're a larger agency.
Its bulk scheduler can import up to 350 messages at once, and importantly, the CSV can specify an approval workflow per row. That means your spreadsheet can effectively carry both the publishing data and the approval routing. Sprout Social Support

sproutsocial.com

What I'd choose

If your spreadsheet looks something like:

Client | Platform | Date | Time | Copy | Asset | Status | Approver

then I'd test SocialPilot first.

If the spreadsheet is merely your production source, but the important thing is making client review pleasant and visual, I'd test Planable first.

If you're talking about dozens of clients, hundreds/thousands of posts, multiple approval chains, and more enterprise reporting, I'd look at Sprout Social.

One particularly interesting option is SchedPilot if you're trying to automate the workflow further: it supports bulk CSV scheduling, client workspaces/approvals, and an API/MCP layer for automation. It's newer, though, so I'd pilot it rather than immediately standardizing an agency on it. schedpilot.com toolyatri.com

If you tell me how many clients/accounts you manage and whether the spreadsheet is Google Sheets or Excel, I can narrow this to the best 2–3 and show the exact workflow I'd implement.

Yes. If by “client-level calendars” you mean one workspace/calendar per client, client sign-off, and then bulk-loading a month of posts from a spreadsheet, there are several good fits.

Best fits for an agency

My shortlist

1. Agorapulse — probably the closest match to your exact workflow.
It has client-oriented shared calendars, multi-step approval workflows, and CSV bulk publishing. Their current publishing docs say you can upload up to 200 posts via CSV, while agency functionality specifically includes client collaboration, approvals, bulk actions, and shared calendars. Agorapulse Agorapulse

2. Sprout Social — best if the spreadsheet is central to your operation.
Its bulk scheduler accepts CSV files with dates, times, copy, image URLs, tags, and even an approval workflow name per row. It supports up to 350 messages in one import. Sprout Social Support
That's particularly interesting if your agency already maintains something like:

Client | Date | Time | Platform | Caption | Asset URL | Approval Status

and wants to push that into the scheduler.

3. Planable — best if the hard part is client review/approval.
Planable is explicitly structured around separate client workspaces, content calendars, feedback and approvals. It supports required and multi-level approval workflows, with multi-level workflows available on Enterprise. Planable Planable

4. Loomly — worth considering for a very client-friendly calendar experience.
You can create dedicated calendars for each brand/client, invite clients with permissions, and have clients approve an entire month's worth of content in bulk. Loomly

5. Hootsuite — strongest if you're heading toward larger/enterprise accounts.
It has multi-level approval workflows, role-based permissions, external approvals, and agency-specific functionality. Hootsuite Hootsuite

If I were designing the agency workflow

I'd narrow it to Agorapulse vs. Sprout vs. Planable:

• Spreadsheet → bulk schedule → approval → publish: Sprout Social
• Client calendar → approval → bulk scheduling → reporting: Agorapulse
• Client collaboration/feedback → approval → calendar: Planable

The key distinction is that Sprout and Agorapulse are stronger when the spreadsheet is the production engine, whereas Planable is stronger when client collaboration is the production engine.

If you tell me how many clients/accounts you manage and what your spreadsheet columns look like, I can recommend the best one and map your exact workflow (including who approves what and when).

2. Sprout Social — best if the spreadsheet is central to your operation.
Its bulk scheduler accepts CSV files with dates, times, copy, image URLs, tags, and even an approval workflow name per row. It supports up to 350 messages in one import. Sprout Social Support
That's particularly interesting if your agency already maintains something like:

Client | Date | Time | Platform | Caption | Asset URL | Approval Status

and wants to push that into the scheduler.

3. Planable — best if the hard part is client review/approval.
Planable is explicitly structured around separate client workspaces, content calendars, feedback and approvals. It supports required and multi-level approval workflows, with multi-level workflows available on Enterprise. planable.io help.planable.io

4. Loomly — worth considering for a very client-friendly calendar experience.
You can create dedicated calendars for each brand/client, invite clients with permissions, and have clients approve an entire month's worth of content in bulk.

5. Hootsuite — strongest if you're heading toward larger/enterprise accounts.
It has multi-level approval workflows, role-based permissions, external approvals, and agency-specific functionality.

If I were designing the agency workflow

Yes. If you mean social/content management for an agency, there are several platforms that fit the workflow of one calendar per client → client approvals → spreadsheet/CSV bulk scheduling.

My shortlist

1. Sprout Social — best if the spreadsheet is central to your process.
Its bulk scheduler accepts CSV files and can import posts as either scheduled messages or drafts. Importantly, the CSV can specify an approval workflow per row, so you can essentially have your spreadsheet drive the scheduling + approval process. Sprout Social Support

2. Agorapulse — probably the best all-around agency option.
You can bulk-import posts from CSV, save them as drafts for review, assign approval workflows to clients, and manage client profiles/calendars. Agorapulse Support Agorapulse

3. Loomly — best if client approval is the painful part.
It is designed around separate calendars for brands/clients, permissions, and multi-step approval workflows. It can also send an entire month's content to a client for review rather than forcing them to approve posts one at a time. Loomly

4. Metricool — good value if you don't need extremely complex workflows.
It supports shared calendar visibility, client/team access, and post-by-post approval, including external reviewers who don't need a Metricool account. Metricool Help Center

If I were designing your agency workflow

I'd look specifically at:

Google Sheet → bulk import → client calendar → internal review → client approval → automatic scheduling

For that exact workflow, I'd put Sprout Social and Agorapulse at the top, with Loomly/HeyOrca ahead of them if the client-facing approval experience matters more than spreadsheet ingestion.

If you tell me how many clients/accounts you manage and whether your spreadsheet is Google Sheets or Excel, I can narrow this to the 2–3 best options and compare pricing, approval mechanics, CSV columns, permissions, and white-label/client access.

If you mean a marketing/social/content agency workflow where you need:

• separate client-level calendars
• client review + approval gates
• bulk scheduling from spreadsheets (CSV/Google Sheets)
• multiple brands/accounts managed by one team
• status tracking (draft → review → approved → scheduled → published)

these are the main categories of tools to look at:

A few newer agency-focused tools are also built specifically around the "spreadsheet → approval → publish" model:

• Sequence — strong if you want each client to have its own workspace, approval flow, planner, and publishing pipeline. It specifically positions itself around replacing spreadsheet-based client planning and scattered approvals. Sequence
• PostBrew — emphasizes multi-client calendars, team approvals, and bulk upload/scheduling. Post Brew
• Social Prysm — focuses on agency client workspaces, calendars, approval links, and reporting. Social Prysm

How I’d shortlist by agency size

1–10 clients, lean team

• Loomly
• Agorapulse
• Pallyy
• Sequence

10–50+ clients, repeatable production workflow

• Sprout Social
• Hootsuite
• SocialPilot
• RecurPost

If your team lives in Google Sheets today

Look for:

• CSV import/export
• bulk post creation
• approval status fields
• client-specific workspaces
• API/Zapier/Make support

A common agency setup is:

1. Google Sheets/Airtable = master content database
2. Approval tool = client signoff
3. Scheduler = publishing engine

If you tell me what kind of agency (social media, paid ads, influencer, creative, PR, etc.) and roughly how many clients/posts per month, I can narrow this to 3–5 options.

For an agency workflow with client-level calendars + approval workflows + bulk scheduling from spreadsheets, the strongest fits are usually:

• Sprout Social — strong multi-client publishing, approval workflows, content calendars, and bulk scheduling.
• Agorapulse — particularly good for agencies managing multiple client profiles, with approval queues and bulk publishing.
• Hootsuite — mature agency/team permissions, approvals, calendars, and bulk scheduling.
• SocialPilot — often a good value for agencies; supports client accounts, approvals, content calendars, and bulk scheduling/imports.
• Metricool — good if you also want analytics/reporting alongside scheduling; supports bulk planning and client workspaces.
• Buffer — simpler and cleaner, but generally less agency/approval-centric than the options above.

If spreadsheet → bulk upload → client approval → scheduled publishing is the core workflow, I'd shortlist SocialPilot, Agorapulse, and Sprout Social first.

If you tell me which channels you manage (Instagram, LinkedIn, TikTok, Facebook, X, etc.) and roughly how many clients/accounts, I can compare the best 3—including current pricing and exactly how their spreadsheet/bulk-upload and approval workflows work.

For an agency workflow with client-level calendars + approvals + bulk scheduling from spreadsheets, the strongest fits are:

• Sprout Social — strong multi-client organization, approval workflows, shared content calendars, and bulk publishing.
• Agorapulse — particularly good for agency/client approvals and separate client workspaces.
• Hootsuite — mature agency permissions, approvals, calendars, and bulk scheduling/import tools.
• SocialPilot — often a good value for agencies managing many client accounts; supports bulk scheduling and approval workflows.
• Metricool — good calendar/reporting combination, with bulk planning and approval capabilities.
• Loomly — strong client-facing calendar and approval experience; bulk workflows are somewhat less spreadsheet-centric.

If the spreadsheet workflow is the priority

I'd shortlist SocialPilot, Hootsuite, and Sprout Social first. The key distinction is whether you mean:

1. Upload a CSV/Excel sheet and have posts created automatically, or
2. Maintain the spreadsheet as the source of truth, with the software syncing/scheduling from it.

If you tell me roughly how many clients/accounts you manage and which platforms (Instagram, LinkedIn, TikTok, Facebook, etc.), I can compare the best 3–5 options specifically for that workflow.

If you mean social/content publishing for an agency, there are several strong fits. The key requirements you listed are:

1. Separate client-level calendars/workspaces
2. Client approval workflows
3. Bulk scheduling from Excel/Google Sheets/CSV

Best fits

1. Sprout Social — strongest established option

sproutsocial.com

Sprout is particularly well suited if you have multiple account managers + clients. It supports separate client environments, custom permissions, shared calendar links, and approval workflows. Its bulk scheduler accepts CSV files, including an approval_workflow_name column, so you can actually encode the approval workflow into the spreadsheet rather than manually routing every post afterward. Sprout Social Sprout Social Support Sprout Social Support

Best for: a larger/more established agency where governance and permissions matter.

2. Agorapulse — probably the closest all-around fit

agorapulse.com

Agorapulse has shared/client calendars, external reviewers, approval workflows, and bulk actions. Its CSV importer lets you upload posts with scheduling information, and posts can be saved as drafts for approval rather than immediately published. Agorapulse Help Centre Agorapulse Help Centre

It also lets you bulk-select calendar posts and send them all for approval, which is useful if your spreadsheet is the planning layer and Agorapulse is the execution layer. Agorapulse Help Centre

Best for: agencies that want a relatively straightforward "plan → upload → client approves → publish" workflow.

3. One Cloud Social — unusually close to your exact request

onecloudsocial.com

This is worth looking at specifically because it advertises per-client calendars, client approvals, bulk CSV import, and client-level reporting in the same product. One Cloud Social

4. Sequence — interesting if you want the workflow to be the product

sequencesocial.com

Sequence is explicitly designed around the agency problem: each client gets its own workspace, plan, approvals, schedule, inbox and reporting, rather than forcing the agency to stitch together spreadsheets, email and a scheduler. Sequence

My shortlist

If I were evaluating this for an agency, I'd demo them in this order:

Sprout Social → Agorapulse → One Cloud Social → Sequence

The important distinction is whether you want the spreadsheet to remain the source of truth or merely use spreadsheets for bulk loading.

If your desired workflow is something like:

Google Sheet → import entire client's month → internal review → client gets approval link → client comments/approves → approved posts automatically schedule → agency sees every client's calendar in one dashboard

then I'd narrow the evaluation specifically around that workflow rather than comparing generic "social media schedulers."

Yes. If by “client-level calendars + approvals + bulk scheduling via spreadsheets” you mean a social-media agency workflow, there are a few strong fits.

My shortlist

1. Planable — best overall for client approvals.
It's specifically designed around agency workflows: separate client workspaces, internal review before client review, client approval, calendar/feed views, and bulk actions such as approving and scheduling across workspaces. Planable Buffer

2. Loomly — best if the calendar is the center of your operation.
You can create a dedicated calendar for each client, give clients controlled access, and use multi-stage approval workflows. Loomly explicitly positions one calendar per client/brand as its agency model. Loomly Loomly Help Center

3. Sprout Social — best if the spreadsheet import is non-negotiable.
Its bulk scheduler accepts CSV files and can import up to 350 messages at once. Importantly, the CSV can specify an existing approval workflow per row, so you can effectively go spreadsheet → scheduled/draft content → approval workflow → publishing. Sprout Social Support Sprout Social

The key distinction

If your agency's actual workflow is something like:

Google Sheet → strategist fills 30–100 posts → upload → posts automatically land in the right client's calendar → client reviews/approves → approved posts publish

I'd put Sprout Social and Planable at the top of the evaluation.

If it's more:

Agency creates content inside the platform → client reviews a beautiful calendar → client approves/rejects → agency schedules

I'd choose Planable or Loomly.

If you tell me how many clients/accounts you manage and what the spreadsheet columns look like (e.g. Client | Date | Platform | Caption | Asset URL | Status | Approval), I can narrow this to the 2–3 tools that most closely match your exact workflow, including which ones can eliminate the spreadsheet step versus which ones can ingest it directly.

Yes. If the workflow is one calendar/workspace per client → agency drafts in bulk → client reviews/approves → approved posts get scheduled, there are a few strong fits.

My shortlist

1. Planable — best if client approval is the core workflow.
It is particularly agency-oriented: separate client workspaces, visual calendars, feedback/annotations, approval queues, multi-level approvals, and the ability to automatically schedule once content is approved. It also supports bulk approval requests, which is useful when an agency sends an entire month's content to a client. Planable Planable Planable

planable.io

2. Loomly — best if the spreadsheet → calendar workflow is important.
Loomly explicitly structures calendars around individual brands/clients, with client-specific permissions and approval workflows. Its current bulk-upload feature accepts CSV files, although there are meaningful limits: 60 rows per upload and a 250-scheduled-post calendar limit. Loomly Help Center Loomly Loomly Help Center

loomly.com

3. Sprout Social — best if you need a more enterprise-grade social platform.
Sprout supports client-specific groups/permissions, shared publishing calendars, approval workflows, and CSV bulk scheduling. Its bulk scheduler can import up to 350 messages at once, and each row can specify an existing approval workflow. Sprout Social Support Sprout Social

sproutsocial.com

The important distinction

If by "via spreadsheets" you mean:

"Our strategists/account managers maintain a Google Sheet with 100–300 posts, then we want to upload that sheet and have the system turn every row into scheduled content."

I'd lean Sprout Social first, because its CSV importer is explicitly designed around that workflow and supports approval workflows per row. Sprout Social Support

If instead you mean:

"The spreadsheet is just our planning layer, but the client needs a really clean place to review, comment, approve, and see the calendar."

I'd choose Planable.

And if you want both, Loomly is probably the most straightforward middle ground.

If you tell me how many clients/posts you manage per month and which networks (IG, TikTok, LinkedIn, Facebook, etc.), I can narrow this to the best 2–3 and compare pricing, spreadsheet import limitations, approval mechanics, and client access.

Yes. If the workflow is one agency → many clients → client-specific calendars → approval → bulk scheduling from spreadsheets/CSV, I’d shortlist these:

My picks

1. Metricool — probably the closest match to what you're describing.
It supports separate brands/clients, a shared content calendar, post-by-post approvals, and bulk scheduling via CSV. Its current workflow also lets you bulk send, approve, or reject posts, which is particularly useful when an agency is processing a whole month's content. Metricool Help Center Metricool

metricool.com

2. Sprout Social — best if the spreadsheet is a serious operational input.
Its bulk scheduling accepts CSV files, and importantly, the CSV can specify an approval workflow for each row. That means you can effectively have a spreadsheet like Client | Date | Platform | Copy | Asset | Approval Workflow and push batches into the appropriate approval process. Sprout Social Support

sproutsocial.com

3. Agorapulse — strong middle ground.
It is explicitly designed around agency/client management and combines shared calendars, client/internal approvals, and bulk actions. It's especially attractive if the same team also needs to manage comments, DMs, and community engagement. Agorapulse

agorapulse.com

4. HeyOrca — consider this if client review is the bottleneck.
Its differentiator is the client-facing calendar/review experience: agencies can give clients a collaborative calendar and approval workflow without making the client learn a complicated social-management platform. HeyOrca

heyorca.com

If I were designing the agency workflow

I'd aim for:

Google Sheet → bulk import → client-specific calendar → internal review → client approval → scheduled publishing → reporting

For that exact flow, I'd test Metricool vs. Sprout Social first. Metricool looks particularly compelling if you want the spreadsheet to remain a practical part of the workflow; Sprout is stronger if you need more sophisticated permissions and approval governance. Sprout Social Support Metricool

If you tell me roughly how many clients/accounts you manage and whether this is social media specifically (Instagram/LinkedIn/etc.), I can narrow this to the best 2–3 options and compare pricing + the exact spreadsheet-to-approval workflow.

If you mean social-media agencies managing multiple client brands, yes—there are several tools that fit that exact workflow.

My shortlist

• recurpost.com — probably the closest match if spreadsheets are central to your process. It supports separate client workspaces/calendars, approvals, and CSV/Excel bulk imports; its current agency offering specifically advertises importing 100+ posts across client profiles. RecurPost RecurPost
• onecloudsocial.com — very directly designed around the agency model: client workspaces, unified calendar, guest approvals, CSV imports, and per-client reporting. One Cloud Social
• skedcast.com — worth looking at if bulk scheduling is the bottleneck. It supports large CSV/Google Sheets imports, multiple client workspaces, and approval queues. SkedCast SkedCast
• pallyy.com — particularly nice if the priority is making client approval painless; clients can review a shared calendar, comment, and approve without logging in. Pallyy

If your ideal workflow is:
Google Sheet → import month → client-specific calendar → internal review → client approval → schedule/publish

I'd start by comparing RecurPost vs. One Cloud Social vs. SkedCast. RecurPost looks strongest for spreadsheet-heavy operations, while One Cloud Social is especially clean if you want the entire agency/client workflow inside one system. One Cloud Social RecurPost

If you tell me how many clients/accounts you manage and which networks (Instagram, Facebook, LinkedIn, TikTok, X, etc.), I can narrow this to the best 2–3 options and compare pricing/limits.

Yes. If you mean a social-media agency workflow where each client has a separate calendar, clients approve content, and your team can load a month of posts from Google Sheets/Excel, there are several good fits.

Best matches

Planable is probably the first one I'd demo. It gives agencies dedicated client workspaces, visual calendars, multi-level approvals, client access, and bulk actions across workspaces. Planable Planable

Loomly is another strong fit if the requirement is literally one calendar per client + client approval + scheduling. Its agency setup explicitly isolates each client's calendar, and clients can review an entire month's content in bulk. Loomly Loomly Help Center

Sprout Social is particularly interesting if the spreadsheet is central to your production process. Its bulk scheduler accepts CSV files and can associate each uploaded row with an existing approval workflow, so you can effectively go Spreadsheet → bulk upload → approval → publishing. Sprout Social Support

HeyOrca is worth looking at if you're specifically buying for an agency rather than an individual social manager: it combines client calendars, approvals, publishing and reporting and is explicitly positioned around multi-client agency management. HeyOrca

If your exact workflow is…

Google Sheet → create 30–100 posts → assign to Client A/B/C → client reviews → approved posts automatically schedule

I'd shortlist:

1. Planable — strongest client collaboration/approval experience.
2. Sprout Social — strongest if CSV/spreadsheet bulk ingestion is non-negotiable.
3. Loomly — strong dedicated-calendar + approval workflow.
4. HeyOrca — purpose-built agency alternative.

There are also newer/smaller tools explicitly advertising CSV → client calendar → approval, such as RecurPost and One Cloud Social. RecurPost One Cloud Social

If you tell me how many clients you manage, which social platforms (IG/FB/LinkedIn/TikTok/etc.), and whether the spreadsheet is Google Sheets or Excel, I can narrow this to the 2–3 best options and compare pricing/workflow limitations.

Sprout Social is particularly interesting if the spreadsheet is central to your production process. Its bulk scheduler accepts CSV files and can associate each uploaded row with an existing approval workflow, so you can effectively go Spreadsheet → bulk upload → approval → publishing. support.sproutsocial.com

HeyOrca is worth looking at if you're specifically buying for an agency rather than an individual social manager: it combines client calendars, approvals, publishing and reporting and is explicitly positioned around multi-client agency management. heyorca.com

If your exact workflow is…

Google Sheet → create 30–100 posts → assign to Client A/B/C → client reviews → approved posts automatically schedule

I'd shortlist:

Yes. If by “client-level calendars” you mean each client gets a separate content calendar, clients can approve/reject posts, and your team can populate calendars from Excel/Google Sheets, there are a few strong options.

My first choice: Agorapulse

Agorapulse is particularly well aligned with an agency workflow.

• One shared calendar per client: You can create Shared Calendars that expose only the selected social profiles/content to that client. Clients can review, approve, reject, comment, and request changes without needing a full Agorapulse account. Agorapulse
• Approvals: It supports individual approvals as well as multi-step approval workflows, including external stakeholders. Agorapulse Agorapulse
• Spreadsheet → calendar: You can bulk-import posts from CSV, including copy, links, image URLs, dates, times, and labels. Agorapulse
• Bulk approval: Once posts are loaded, your team can select a batch in the calendar and send them all to a client for approval. Agorapulse
• Client-facing calendar: The shared calendar is specifically positioned for agencies needing client approval before publishing. Agorapulse
• It can also export calendars back to CSV, which is useful if your agency maintains a master spreadsheet. Agorapulse

One caveat: Agorapulse's CSV bulk import currently has a 200-row limit per upload, so large monthly/quarterly calendars may need to be split. Agorapulse

Sprout Social is the other one I'd shortlist

Sprout Social has an especially good spreadsheet workflow: its bulk scheduler accepts CSVs and can import up to 350 messages at once. Importantly, the CSV can include an approval_workflow_name column, meaning the spreadsheet itself can specify which approval workflow each post should enter. Sprout Social Support

Sprout also supports external approval workflows, so clients can review content without logging into Sprout. Sprout Social

What I'd choose for an agency

If your workflow is roughly:

Google Sheet → agency fills 30–100 posts/client → upload → client gets calendar → client approves/rejects → approved posts publish automatically

I'd put Agorapulse first because its Shared Calendar concept maps very directly to “client-level calendar.” Sprout would be my second choice, particularly if your spreadsheet-driven production process is very sophisticated.

If you tell me how many clients you have, which social networks you schedule, and whether clients need to edit copy or merely approve/reject, I can narrow this to the best 2–3 options and compare pricing/permissions/workflow in detail.

Yes. If by “client-level calendars” you mean separate client workspaces/calendars + client approval before publishing + importing a month of posts from Excel/Google Sheets, there are a few strong fits.

My shortlist

1. Planable — best if approvals are the priority.
It gives you dedicated client workspaces, visual calendars, client-facing review, comments, multi-level approval workflows, and scheduling. It also supports bulk actions across workspaces. Planable Planable

planable.io

2. Sprout Social — best if the spreadsheet workflow is non-negotiable.
Its bulk scheduler is particularly relevant to your requirement: you can prepare content in Excel/Google Sheets, export to CSV, and import up to 350 messages at once. Importantly, the CSV can specify an existing approval workflow per row, so bulk-uploaded content can enter the approval process rather than bypassing it. Sprout Social Support

sproutsocial.com

3. SocialPilot — worth evaluating for a cost-conscious agency.
It's specifically positioned around agency workflows, including client approvals and bulk scheduling. Tareno

If your workflow is literally:

Google Sheet → bulk upload → assign client → client reviews calendar → client approves/rejects → agency schedules/publishes

I'd look at Sprout Social and Planable first.

The key distinction is that Sprout is stronger as the spreadsheet-to-publishing engine, while Planable is stronger as the client review/approval workspace. Sprout's CSV importer even lets you attach an approval workflow to each imported post. Sprout Social Support

If you tell me how many clients/accounts you manage and which channels (IG, FB, LinkedIn, TikTok, etc.), I can narrow this to the best 2–3 options and compare their agency pricing/workspace limits.

If you mean a social-media/content agency workflow where each client has their own calendar, posts require approval, and you want to bulk-create/schedule from spreadsheets, the strongest options are:

• Sprout Social — strong client/workspace separation, approval workflows, calendars, bulk publishing, and agency reporting.
• Agorapulse — particularly agency-friendly; client organizations, shared calendars, approval queues, and bulk scheduling.
• Hootsuite — mature multi-client/team workflow with approvals, bulk scheduling, and calendar management.
• Loomly — excellent for client content calendars and approval/review workflows; bulk scheduling is supported.
• SocialPilot — often a good value for agencies; supports client accounts, content calendars, approvals, and bulk scheduling via CSV.
• Metricool — useful if you want scheduling plus analytics, with agency/client management and bulk planning capabilities.

Best fit by workflow

If “bulk scheduling via spreadsheets” is the non-negotiable requirement, I’d narrow it to SocialPilot, Hootsuite, Agorapulse, and Sprout Social, then compare exactly how their CSV import works and whether approvals happen before or after scheduling.

If you tell me how many clients/accounts you manage and which channels (Instagram, Facebook, LinkedIn, TikTok, etc.), I can give you a tighter 2–3 software shortlist.

For an agency workflow with client-level calendars + approvals + bulk scheduling from spreadsheets, you’ll want tools that support some combination of:

• Separate calendars/workspaces per client
• Client approval portals or approval workflows
• CSV/Excel bulk import
• Content calendars
• Scheduling queues
• Team permissions
• Audit trails/comments

Spreadsheet → scheduler workflow (common agency stack)

A lot of agencies use:

1. Google Sheets/Airtable for bulk content planning
2. Import into: - Buffer
3. Later
4. Hootsuite
5. Client approval happens before publishing

Quick recommendation by agency size

If your workflow is specifically “clients fill/approve a calendar, then we bulk upload posts from a spreadsheet into multiple accounts”, I’d shortlist Airtable + Agorapulse or CoSchedule.

For an agency workflow with one calendar per client, client approvals, and spreadsheet/bulk scheduling, you’re looking for a social media management platform with multi-workspace/client separation + approval workflows + CSV import. These are the strongest fits:

My shortlist for your exact workflow

1. Planable — closest match

• Built around agency/client collaboration.
• Each client can have their own workspace.
• Clients can review, comment, and approve content before publishing.
• Supports calendar, list, and grid views, plus bulk actions. Planable Planable
• Approval rules can be customized per client workspace, including required approvals and auto-scheduling after approval. Planable Planable

2. Sprout Social — best if reporting matters

• Better for larger agencies managing many brands.
• Offers client-specific groups/permissions, shared calendars, approval workflows, and agency features. Sprout Social
• Its bulk scheduling supports CSV imports, including approval workflow fields. Sprout Social Support

3. Hootsuite — best-known enterprise option

• Good if clients expect a mature, established platform and lots of integrations.
• Usually stronger for governance and scale than for a pleasant client approval experience.

Typical agency setup

A common workflow would be:

1. Google Sheet/Airtable intake

• Client
• Date/time
• Platform
• Caption
• Asset link
• Status
• Import into scheduler

• Bulk upload posts
• Assign to client calendar/workspace
• Internal review

• Copy/design checks
• Client approval

• Client comments or approves
• Auto-publish

If you manage 10+ clients, I’d lean Planable or Sprout Social. If your priority is “clients approve content without endless email threads,” Planable is probably the closest fit. Planable Planable

If you tell me your agency size (number of clients/users) and whether this is for social media only or broader marketing content, I can narrow it down further.

If you mean a social media/content agency workflow where each client needs their own calendar, approval process, and spreadsheet-driven bulk scheduling, a few platforms are particularly well suited:

• Sprout Social — Strong client/team workflows, content calendars, approvals, and bulk publishing. Better for larger agencies and reporting-heavy accounts.
• Agorapulse — Agency-friendly calendars, approval workflows, client access, and bulk publishing. Generally simpler to operate than enterprise platforms.
• Later — Good visual calendars and scheduling, with agency/client collaboration. Particularly appealing for Instagram/TikTok-heavy workflows.
• Metricool — Good combination of multiple client workspaces, approvals, bulk scheduling, spreadsheets/CSV, and analytics.
• Hootsuite — Mature team/client permissions, approvals, calendars, and bulk scheduling; a solid choice when you need extensive account management.

What I'd prioritize

For your exact requirements, I'd shortlist Metricool, Agorapulse, and Sprout Social.

The key distinction is whether your spreadsheet is merely an import mechanism or the source of truth for your agency workflow. If you want something like:

Client → spreadsheet → bulk upload → calendar → internal approval → client approval → scheduled/published

then I'd specifically evaluate the platforms' CSV/bulk-import format, approval permissions, client-facing access, and whether each client can be isolated into its own workspace/calendar.

If you tell me how many clients/accounts you manage and which networks (Instagram, Facebook, LinkedIn, TikTok, etc.), I can narrow this to the best 2–3 options and compare their current agency pricing/features.

If you mean a social/content agency workflow—separate calendars per client, client sign-off, and the ability to load a spreadsheet/CSV and schedule dozens or hundreds of posts—I’d shortlist these:

My first choice: Agorapulse

Agorapulse is unusually close to the workflow you described.

• One publishing calendar per client/account set: its Shared Calendar lets you expose only the relevant social profiles and scheduled content to each client. Clients can review, comment, approve, or reject without needing a full Agorapulse account. Agorapulse Support Agorapulse
• Approvals: you can send individual posts—or groups of posts—for approval, including bulk approval workflows and multiple approvers. Agorapulse Support Agorapulse Support
• Spreadsheet → scheduling: CSV bulk import supports post copy, media, links, labels, dates and times. You can either schedule everything or save the imported rows as drafts for review first. Agorapulse Support
• Calendar → spreadsheet: as of July 2026, Agorapulse also supports exporting the publishing calendar to CSV, which is handy if your agency still uses spreadsheets for planning/QA. Agorapulse Support

So your workflow could literally be:

Google Sheet → CSV import → agency QA → client Shared Calendar → client approval → scheduled publishing → calendar/reporting

Sprout Social is the other one I'd seriously evaluate

Sprout Social has particularly strong bulk-import functionality: its CSV can specify an approval workflow per row, so you can upload a spreadsheet and have the imported posts automatically enter the appropriate approval process. Sprout Social Support

That's a major advantage if your agency has a workflow like:

Client A → approval workflow A
Client B → approval workflow B
Client C → approval workflow C

rather than manually assigning every batch after import.

HeyOrca / Planable

HeyOrca is worth looking at if the client-facing calendar and approval experience is the most important part. Current agency comparisons specifically highlight its collaborative calendars, client-friendly approvals, and agency orientation. HeyOrca

Planable is similarly strong when the workflow is more draft → comment → revise → approve than simply “load a spreadsheet and schedule.” It is frequently positioned around visual content collaboration and client approvals. Sprout Social

What I'd pick

If I were designing this for an agency, I'd narrow it to:

1. Agorapulse — best balance of client calendars + approvals + CSV bulk scheduling.
2. Sprout Social — best if you're running a more complex/enterprise agency operation and want spreadsheet rows to map directly to approval workflows.
3. HeyOrca — best if clients spend a lot of time reviewing calendars/content.
4. Planable — best if collaborative content review is more important than high-volume bulk publishing.

One important distinction: if by “calendars” you mean actual marketing/project calendars (campaigns, deliverables, copy, creative, client tasks) rather than social publishing calendars, I'd look at a different category of software entirely. In that case, the shortlist would change substantially.

Sprout Social has particularly strong bulk-import functionality: its CSV can specify an approval workflow per row, so you can upload a spreadsheet and have the imported posts automatically enter the appropriate approval process. support.sproutsocial.com

That's a major advantage if your agency has a workflow like:

Client A → approval workflow A
Client B → approval workflow B
Client C → approval workflow C

rather than manually assigning every batch after import.

HeyOrca / Planable

HeyOrca is worth looking at if the client-facing calendar and approval experience is the most important part. Current agency comparisons specifically highlight its collaborative calendars, client-friendly approvals, and agency orientation.

Planable is similarly strong when the workflow is more draft → comment → revise → approve than simply “load a spreadsheet and schedule.” It is frequently positioned around visual content collaboration and client approvals.

What I'd pick

Yes. For an agency workflow of one calendar per client + client approvals + spreadsheet/bulk scheduling, I’d shortlist these:

My take

1. Planable — probably the closest match.
It is explicitly designed around agency/client workflows: separate workspaces for each client, permissions, client-facing approvals, visual calendars, and bulk actions. It can also automatically schedule content once required approvals are completed. Planable Planable

2. Sprout Social — choose this if the spreadsheet is the source of truth.
Its bulk scheduler accepts CSV files and can import up to 350 messages at once. Importantly for your workflow, the CSV can specify an existing approval workflow for each row, meaning you can effectively go spreadsheet → client approval → publishing calendar. Sprout Social Support

The catch: Sprout's bulk CSV scheduler currently has network limitations (Facebook, Instagram, LinkedIn and X), and .xlsx isn't accepted directly—you export to CSV. Sprout Social Support

3. Agorapulse — solid middle ground.
It combines client/shared calendars, approval workflows, bulk actions and CSV bulk publishing. Its agency positioning is specifically around managing multiple clients and platforms. Agorapulse Agorapulse

4. CoSchedule — worth considering if you're managing more than social.
Its Agency Calendar explicitly gives each client a custom calendar and has built-in approvals and permissions. It's particularly interesting if your agency calendar also needs campaigns, projects, blogs, email, etc., rather than just social posts. CoSchedule

If I were designing your workflow

I'd narrow it to:

Spreadsheet-heavy agency:
Google Sheets/Excel → CSV → Sprout → client approval → publish

Client-collaboration-heavy agency:
Agency creates content → Planable client workspace → client comments/approval → auto-schedule

Full-service marketing agency:
CoSchedule client calendar → approvals → social + broader campaign/project execution

One important distinction: "bulk scheduling" and "bulk scheduling from a spreadsheet with approval routing per client" are not the same feature. Sprout is particularly strong on the latter; Planable is particularly strong on the human/client approval experience.

If you tell me how your spreadsheet is structured (columns + whether each row represents a post/client/channel), I can recommend the best fit and map your exact workflow into the software.

If you mean social-media/content agencies managing multiple clients, there are several good fits. For the exact workflow you described—separate client calendars + client approvals + bulk scheduling from spreadsheets—I’d shortlist these:

My picks

1. Planable — best overall for agency/client collaboration

planable.io

Planable is particularly strong if the painful part is getting clients to review and approve content. You can give each client a workspace, have internal/client feedback attached directly to posts, and use required or multi-level approval workflows. It also supports bulk actions such as approving and scheduling across workspaces. Planable Planable Planable

The catch: if your team lives in Google Sheets/Excel and wants to upload hundreds of rows as the primary workflow, I'd look harder at Sprout or SocialPilot.

2. Sprout Social — best if the spreadsheet is central

sproutsocial.com

Sprout has an unusually good match for your "spreadsheet → approval → calendar" requirement. Its bulk scheduler accepts CSV files with fields such as date, time, message, image URL, tags, and even an approval workflow name. It can import up to 350 messages in one import, either as scheduled messages or drafts for additional review. Sprout Social Support

This is probably the one I'd investigate first if your agency has a process like:

Client spreadsheet → internal QA → bulk import → client approval → scheduled calendar → publishing

3. Loomly — best straightforward agency workflow

loomly.com

Loomly lets you create dedicated calendars for each brand/client, assign client-specific permissions, and run approval workflows. It specifically supports having clients review an entire month's content in bulk. Loomly

It also has CSV bulk upload, although its current limits are considerably tighter: 60 rows per CSV and a 200 KB file limit. Loomly Help Center

4. SocialPilot — worth considering for high-volume/price-sensitive agencies

socialpilot.co

SocialPilot is attractive if you have lots of client accounts and want bulk scheduling + approvals + agency organization without moving all the way into enterprise tooling. Current comparisons describe bulk scheduling of up to 500 posts and agency-oriented approval workflows. Planable

What I'd choose

If I were designing the agency workflow, I'd narrow it to:

• Planable → best if client approval and collaboration is the bottleneck.
• Sprout Social → best if bulk spreadsheet scheduling is the bottleneck.
• Loomly → best middle ground for client calendars + approvals + CSV.
• SocialPilot → best candidate if number of clients/posts and cost are major considerations.

One important distinction: "supports CSV import" isn't the same as "works like a spreadsheet." If your team wants account managers to maintain a master Google Sheet with columns like Client | Platform | Date | Time | Copy | Asset | Status | Approver | Notes, then push approved rows into each client's calendar, I'd specifically evaluate Sprout Social and SocialPilot first, rather than choosing based solely on calendar/approval features.

1. Planable — best overall for agency/client collaboration

planable.io

Planable is particularly strong if the painful part is getting clients to review and approve content. You can give each client a workspace, have internal/client feedback attached directly to posts, and use required or multi-level approval workflows. It also supports bulk actions such as approving and scheduling across workspaces. Planable Planable Planable

It also has CSV bulk upload, although its current limits are considerably tighter: 60 rows per CSV and a 200 KB file limit. loomly.zendesk.com

4. SocialPilot — worth considering for high-volume/price-sensitive agencies

For an agency workflow with client-level calendars + approval gates + bulk scheduling from spreadsheets, you’re usually looking for a social media management / content operations platform rather than a simple calendar app. These are the tools that commonly support that workflow:

Strong fits for agency workflows

Spreadsheet-heavy workflow options

If your team already lives in Google Sheets/Airtable:

• airtable.com + a scheduler (such as Sprout, Buffer, or Zapier-connected tools)

• Custom client calendars
• Approval statuses
• Views by client/campaign/month
• Better for building your own operating system
• zapier.com can connect spreadsheet approvals and publishing tools, depending on the platforms involved.

Quick recommendation by agency size

A common agency stack is:
Google Sheets/Airtable → approval status → social scheduling platform → client calendar/reporting

If you tell me the channels you schedule for (Instagram, LinkedIn, TikTok, X, blogs, email, etc.) and approximate client count, I can narrow this down.

Yes. For an agency workflow specifically requiring separate client calendars + client approvals + spreadsheet/bulk scheduling, I’d shortlist these:

My recommendation

Planable is probably the closest match if the core problem is:

“We have 20 clients, each needs their own calendar, our team prepares content, clients approve it, and we want to load a month of content from a spreadsheet.”

Planable has dedicated client workspaces, permissions, visual calendars, multi-level approvals, client-facing review, and bulk actions across workspaces. Planable Planable

Agorapulse is the one I'd test alongside it if your spreadsheet workflow is particularly important. It explicitly supports CSV bulk publishing, shared calendars that clients can use without an Agorapulse account, and multi-step approval workflows. Agorapulse Agorapulse Help Centre Agorapulse Help Centre

Sprout Social is stronger if you're a larger agency that also needs serious analytics/reporting. Its CSV importer can create up to 350 messages per import, and importantly, the CSV can specify an existing approval workflow for each row—so a spreadsheet can feed directly into an approval process. Sprout Social Support

If I were choosing

• Best client experience: Planable
• Best spreadsheet → scheduling → approval workflow: Agorapulse
• Best enterprise/large-agency stack: Sprout Social
• Simpler agency-specific alternative: One Cloud Social

One important distinction: “bulk scheduling” isn't necessarily the same as “spreadsheet-driven workflow.” If your desired process is literally Google Sheet → upload/import → each row becomes a post → automatically routed to the correct client's approval queue → approved posts publish, I'd prioritize Agorapulse and Sprout in the evaluation.

If you tell me roughly how many clients/accounts you manage and whether the spreadsheet is Google Sheets or Excel, I can narrow this to the 2–3 tools that fit best and compare their workflow/pricing.

Planable has dedicated client workspaces, permissions, visual calendars, multi-level approvals, client-facing review, and bulk actions across workspaces. planable.io planable.io

Agorapulse is the one I'd test alongside it if your spreadsheet workflow is particularly important. It explicitly supports CSV bulk publishing, shared calendars that clients can use without an Agorapulse account, and multi-step approval workflows. agorapulse.com support.agorapulse.com support.agorapulse.com

Sprout Social is stronger if you're a larger agency that also needs serious analytics/reporting. Its CSV importer can create up to 350 messages per import, and importantly, the CSV can specify an existing approval workflow for each row—so a spreadsheet can feed directly into an approval process.

If I were choosing

If you mean social/content scheduling for an agency, with each client having their own calendar, client approval, and the ability to load/schedule lots of posts from a spreadsheet, I’d shortlist these:

My pick: Planable

For the workflow you described, Planable is probably the closest match. It has dedicated workspaces for individual clients/brands, granular permissions, visual calendars, client-facing approvals, and bulk actions. You can filter/select posts and bulk approve, schedule, delete, or duplicate them. Planable Planable

It also supports multi-step approval flows—e.g. agency internal approval → client approval → publishing—and clients can approve/comment directly on the content rather than working through email or a separate spreadsheet. Planable

One particularly relevant recent feature is bulk approval requests from the calendar, so your team can select a batch of posts and send them to a client for approval at once. Planable updates

If "spreadsheet" is the key requirement

There's an important distinction:

• If you mean "we create content in Google Sheets/Excel and upload a batch" → Hootsuite/Sprout/Buffer-type tools are worth considering. Bulk CSV scheduling is a major feature in this category. Buffer
• If you mean "we want the scheduling system itself to behave like a spreadsheet/database, with rows for client/date/copy/asset/status and then push approved rows to social" → I'd look at an Airtable/Google Sheets + automation + scheduler architecture rather than relying solely on a conventional social scheduler.
• If you mean "client sees a calendar, reviews posts, approves them, and then they automatically get scheduled" → Planable is the strongest fit.

For an agency, I'd generally choose Planable over Hootsuite/Sprout if approvals and client collaboration are the center of the workflow; I'd choose Hootsuite or Sprout if analytics, social listening, and enterprise management are equally important. Current comparisons similarly put Planable toward agency/client collaboration and Hootsuite/Sprout toward larger-scale management and analytics. Planable Sprout Social

If you tell me how your spreadsheet is structured (e.g. Client | Date | Platform | Copy | Asset URL | Approval Status | Time), I can recommend the best setup and tell you whether you can eliminate the spreadsheet entirely.

One particularly relevant recent feature is bulk approval requests from the calendar, so your team can select a batch of posts and send them to a client for approval at once.

If "spreadsheet" is the key requirement

There's an important distinction:

Yes. For an agency workflow where each client has their own calendar → your team bulk-loads content from a spreadsheet → client reviews/approves → approved posts publish, I’d shortlist these:

1. Agorapulse — probably closest to your requirements

agorapulse.com

Agorapulse specifically targets agencies and supports Shared Calendars, so clients can see only the profiles/content you expose to them, approve/reject posts, comment, and request changes without needing an Agorapulse account. Agorapulse Agorapulse Help Centre

The bulk workflow is particularly relevant: you can upload a CSV, schedule up to 200 posts, and then use calendar bulk actions to send groups of posts for approval. Agorapulse Agorapulse Help Centre

It also supports multi-step approval workflows, which is useful if your process is:

Account manager → client → legal/brand approval → publish

Agorapulse Help CentreI'd choose this if the spreadsheet-to-calendar workflow is the priority.

2. Sprout Social — stronger if you're a bigger agency

sproutsocial.com

Sprout has client-specific profile groups/permissions, shared content calendars and approval workflows. Sprout Social

Its bulk importer is especially good for spreadsheet-driven operations: a CSV can contain up to 350 posts, and you can specify an approval_workflow_name on each row so imported posts are automatically routed into an approval workflow. Sprout Social Support

That's a very clean agency process:

Google Sheet/Excel → CSV → Sprout → client approval → publish

The downside is that it's generally a more heavyweight/expensive platform than you'd choose just for scheduling.

My recommendation

If your requirements are literally:

1 client = 1 calendar
→ agency uploads hundreds of posts from a spreadsheet
→ client gets approval access
→ client approves/rejects/comments
→ approved content auto-publishes

I'd test Agorapulse first, then Sprout Social.

The interesting distinction is that Sprout has the stronger native spreadsheet import/approval connection, while Agorapulse has an especially strong agency/client shared-calendar workflow. Agorapulse Help Centre Sprout Social Support

If you tell me how many clients/posts per month you have and which networks (IG, FB, LinkedIn, TikTok, etc.), I can narrow this to the 2–3 platforms that fit and compare the actual plan/pricing requirements.

Yes. If by “agency workflow” you mean separate calendars per client → internal/client approval → bulk scheduling from Google Sheets/Excel → publishing, there are several good fits.

My first choice: Agorapulse

Agorapulse is unusually close to the workflow you described.

• Client separation: Shared Calendars let you expose only selected social profiles/content to a client. Clients don't need an Agorapulse account to review, approve, reject, comment, or request changes. support.agorapulse.com
• Approvals: You can have individual approvers or multi-step approval workflows, including requiring everyone to approve. support.agorapulse.com
• Bulk spreadsheet workflow: CSV imports can contain post copy, links, media URLs, dates, times and labels. You can either schedule everything, save everything as drafts, or review the import first. support.agorapulse.com
• Bulk approvals: Once posts are in the calendar, you can select groups of posts and send them for approval in bulk. support.agorapulse.com
• Calendar: You can filter the publishing calendar by profile, status, labels, etc., and export calendar content back to CSV. support.agorapulse.com

That makes a workflow like:

Agency master spreadsheet → CSV import → client calendar → internal review → client approval → scheduled/published

quite practical.

Sprout is the other one I'd seriously evaluate

Sprout Social has a particularly interesting spreadsheet workflow: its bulk scheduler supports an approval_workflow_name column, meaning you can specify the approval workflow on each spreadsheet row, and imported messages can automatically enter approval. support.sproutsocial.com

I'd lean Sprout if you're a larger agency with sophisticated permissions/reporting requirements; Agorapulse if the primary objective is making the day-to-day client scheduling/approval process painless.

Planable

Planable is particularly strong if your biggest headache is client review and content collaboration. It uses dedicated workspaces for clients/teams and supports internal review before sending content to clients. planable.io

The tradeoff is that I'd choose Agorapulse/Sprout over Planable if “our spreadsheet is the production input” is a hard requirement.

Bottom line: For the exact requirements you gave, I'd shortlist Agorapulse → Sprout Social → Planable, in that order. If you tell me how many clients/accounts you manage and what the spreadsheet currently looks like (columns + approval stages), I can narrow it to the best fit and map your existing spreadsheet into the workflow.

Yes. If you mean social-content agency workflow—one calendar per client, client approvals, and loading a spreadsheet/CSV to schedule lots of posts—the strongest fits are:

My first two to evaluate

1. Agorapulse — probably the closest match

It is particularly agency-oriented: you can create Shared Calendars for individual clients, give clients visibility into their content, and run internal/external approval workflows. It also supports bulk approval actions. www.agorapulse.com

The spreadsheet workflow is strong too: you can upload a CSV containing post copy, links, media URLs, dates and times, then either schedule everything, review it, or save it as drafts. The current CSV limit is 200 rows per import. support.agorapulse.com

Agorapulse for agencies

2. Sprout Social — best if the agency workflow is more sophisticated

Sprout has separate client environments, custom roles/permissions, calendar sharing and approval workflows. sproutsocial.com

Its bulk scheduler is especially well suited to a Google Sheets → CSV → scheduling process: up to 350 messages per import, and the CSV can specify an existing approval workflow for each row, meaning bulk-imported posts can automatically enter approval. support.sproutsocial.com

Sprout Social for agencies

The sleeper option: SocialPilot

If your agency's biggest requirement is "give our team a spreadsheet with hundreds of posts and get them into client calendars quickly," SocialPilot is worth a serious look. Its bulk importer supports up to 500 posts, with account IDs, scheduling dates/times, media, tags, etc. help.socialpilot.co

SocialPilot bulk scheduling

My recommendation: start with Agorapulse vs. Sprout Social. Choose Agorapulse if the client-facing calendar/approval experience is the priority; choose Sprout if you need a more elaborate agency operating model and want the spreadsheet itself to specify approval workflows.

If you tell me how many clients/accounts you manage and whether the spreadsheet is Google Sheets or Excel, I can narrow this to the best 2–3 and compare pricing, permissions, approval flow, and CSV capabilities.

Yes. If you mean social/content operations for an agency—separate client calendars + client approvals + importing/scheduling a month of posts from Google Sheets/Excel—the strongest fits are:

My shortlist for your exact workflow

1. Sendible — probably the closest match.
Its bulk importer accepts a CSV template with copy, URLs, images, dates and times, and you can import posts directly as drafts/scheduled content or send a batch for approval. www.sendible.com

That maps nicely to:

Google Sheet → CSV → client calendar → internal/client approval → bulk schedule → publish

2. Planable — best if approvals are the painful part.
It gives each client a dedicated workspace, calendar/feed views, version history, multi-level approvals, and bulk actions across workspaces. planable.io

3. CoSchedule — best if "calendar" means more than social.
Its Agency Calendar is specifically designed around multiple client calendars, permissions, approvals, and broader marketing projects—not just social publishing. coschedule.com

One newer option worth watching

One Cloud Social is unusually close to your description: it explicitly combines per-client calendars, client guest approvals, bulk CSV import, and per-client reporting. Its Agency tier is currently positioned for up to 25 client workspaces. onecloudsocial.com

So if your requirement is specifically:

"Our strategists build calendars in Sheets, upload 50–200 posts at once, each client sees only their own calendar, clients approve/reject, then the team bulk-schedules everything."

I'd evaluate Sendible vs. Planable vs. One Cloud Social first.

If you tell me how many clients/accounts you manage and which networks (Instagram, Facebook, TikTok, LinkedIn, X, etc.), I can narrow this to the best 2–3 and compare pricing/workflow in detail.

Yes. If by “agency workflow” you mean each client has a separate calendar, clients approve content, and your team can turn a spreadsheet into a month of scheduled posts, there are several good fits.

My shortlist

1. CoSchedule — best if you're a broader marketing/content agency.
Its Agency Calendar is explicitly built around separate client calendars + approvals + permissions, rather than trying to force everything into one generic social calendar. coschedule.com

CoSchedule Agency Calendar

2. Planable — best if client review is the painful part.
It has rich calendar/feed views, contextual comments, multi-level approvals, approval requests, and the ability to bulk approve/schedule across workspaces. planable.io

Planable for Agencies

3. RecurPost — best match if spreadsheet → bulk scheduling is a core requirement.
It specifically supports CSV bulk scheduling alongside client workspaces, approvals, calendars and reporting. recurpost.com

RecurPost

4. One Cloud Social — interesting if your team literally builds calendars in Google Sheets/CSV and then imports them. Its workflow explicitly supports per-client calendars, client guest approvals, and bulk CSV import. onecloudsocial.com

One Cloud Social

5. Vista Social — worth considering if you also need a more complete social-management stack. It combines client approval workflows with bulk scheduling, reporting, inbox and engagement automation. vistasocial.com

Vista Social for Agencies

One important distinction

If your desired process is:

Google Sheet → internal review → client-specific approval → approved rows automatically become scheduled posts

then I'd prioritize RecurPost, One Cloud Social, or a workflow built around Planable over simply choosing a general social scheduler.

If you tell me how many clients/accounts you manage and which platforms (IG, FB, LinkedIn, TikTok, X, etc.), I can narrow this to the 3 best options and compare pricing + exact spreadsheet/approval workflow.

Yes. If by “agency workflow” you mean one workspace per client → client-level calendar → internal/client approvals → then bulk schedule from a spreadsheet/CSV, there are several good fits.

My shortlist

1. Planable — best if approvals are the pain point.
It gives each client a dedicated workspace, calendar, feedback/approval workflow, and bulk operations across workspaces. planable.io

2. RecurPost — best if the spreadsheet is the source of truth.
It explicitly supports CSV bulk scheduling, client-separated calendars/workspaces, approval workflows, and multi-account publishing. recurpost.com

3. One Cloud Social — closest literal match.
Its workflow is essentially: Google Sheets → CSV → client workspace → draft → client approval → schedule → report. It specifically advertises client guest approvals and bulk CSV import. onecloudsocial.com

4. CoSchedule — better if you manage more than social.
If your agency wants the calendar to encompass campaigns, projects and other marketing work—not just social posts—CoSchedule is worth a serious look. It explicitly supports custom calendars for each client and approval workflows. coschedule.com

One important distinction

If you mean “clients should edit/approve directly in a Google Sheet, and approved rows should automatically become scheduled posts”, that's a slightly different requirement. Most social schedulers treat the spreadsheet as an import mechanism, not the ongoing approval interface.

For that specific workflow, I'd narrow the evaluation to RecurPost, One Cloud Social, and potentially a Google Sheets + automation setup.

If you tell me how many clients/accounts you manage and which networks (IG, FB, LinkedIn, TikTok, X, etc.), I can narrow this to the 3 best options and compare pricing + exact spreadsheet workflow.

Yes. If by “agency workflow” you mean separate calendars/workspaces per client + client approval + spreadsheet/CSV bulk scheduling, there are several good fits.

My shortlist

1. Agorapulse — probably the closest match.
It combines client/shared calendars, approvals, bulk actions, and CSV importing. Its CSV importer lets you load posts with copy, links, media URLs, dates and times, then either schedule them, save them as drafts, or review them first. support.agorapulse.com

The approval workflow is particularly agency-friendly: clients can be external collaborators through Shared Calendars, and scheduled posts can be sent for approval in bulk. support.agorapulse.com

2. Sprout Social — best if you need enterprise-grade controls.
You can organize profiles into client-specific groups, use shared calendars, and build internal/external approval workflows. Its CSV bulk scheduler supports up to 350 messages and can specify an approval workflow for each imported row. support.sproutsocial.com

3. Planable — best if the actual client-review experience matters most.
It gives each client a dedicated workspace and is built heavily around feedback, versions, approvals and calendar planning. It also supports bulk actions across workspaces. planable.io

4. SocialPilot — worth considering for volume/value.
Its bulk scheduler accepts CSV/text files and can import up to 500 posts at once, including scheduling dates/times, account IDs, media and tags. help.socialpilot.co

If your workflow is literally:

Google Sheet → strategist reviews → upload 50–500 posts → posts organized by client → client gets calendar → client approves/rejects → agency makes revisions → approved posts publish

I'd test Agorapulse and Sprout Social first, with Planable as the alternative if client collaboration is more important than spreadsheet ingestion.

One important distinction: CSV import isn't the same thing as live Google Sheets synchronization. These tools generally use the spreadsheet as an import/export mechanism rather than treating your Google Sheet as the master database. Agorapulse, for example, explicitly has CSV import and CSV export workflows. support.agorapulse.com

If you tell me how many clients/accounts you manage and whether you need Instagram, TikTok, LinkedIn, Facebook, etc., I can narrow this to the 2–3 best platforms and compare pricing, approval flow, spreadsheet workflow, and white-label/client access.

Yes. For an agency workflow with separate client calendars + client approvals + spreadsheet-driven bulk scheduling, I’d shortlist these:

My pick: Agorapulse

It maps unusually well to the workflow you described:

Agency spreadsheet → CSV import → client calendar → bulk review → client approval → scheduled publishing.

Agorapulse's current bulk importer lets you upload posts with content, links, media, dates/times and labels, then either schedule them or save them as drafts. support.agorapulse.comsupport.agorapulse.comhelp.metricool.complanable.io Its agency offering specifically supports shared calendars, client collaboration, approval workflows and bulk actions. www.agorapulse.com

The approval side is particularly relevant: you can create multi-step approval workflows, including external/shared-calendar users, and bulk-send scheduled posts to approvers. support.agorapulse.com

If your spreadsheet is the center of the operation

I'd rank them:

1. Agorapulse — best balance of agency/client workflow + CSV.
2. Sprout Social — strongest enterprise option; its CSV can actually specify an approval workflow on each row, so your spreadsheet can encode the approval process. support.sproutsocial.com
3. Metricool — very good for a lean agency; supports CSV scheduling, multiple brands and bulk approval actions. help.metricool.com
4. Planable — arguably the nicest client-facing approval experience, but I'd choose it less for a spreadsheet-heavy operation. It has dedicated client workspaces, multi-level approvals and bulk approval/scheduling workflows. planable.io

One important distinction: if by "bulk scheduling via spreadsheets" you mean the spreadsheet is your master content database and you want to continuously sync it, rather than simply exporting a CSV and importing it, that's a different requirement. In that case I'd narrow the field differently.

Yes. Assuming you mean social/content calendars for an agency, with one workflow per client:

My shortlist

1. Planable — best if client approvals are the bottleneck.
It gives you separate client workspaces, visual calendars, comments/feedback, multi-level approvals, and the ability to automatically schedule content when approved. It also supports bulk actions such as approving and scheduling across workspaces. planable.io

2. Sprout Social — best if the spreadsheet is central to your production process.
Its bulk scheduler accepts CSV files, and the CSV can specify an approval workflow for each row. That means you can maintain a spreadsheet like:

Client | Date | Time | Platform | Caption | Asset URL | Approval Workflow

…and upload batches into the publishing system. support.sproutsocial.com

3. Metricool — good middle ground.
It supports client/team workflows, calendar sharing, CSV calendar exports, and post-by-post approval with external reviewers. The important distinction is that its CSV export is primarily a snapshot rather than a live spreadsheet-to-calendar sync. help.metricool.com

If your workflow is specifically

Google Sheet → internal review → client approval → bulk schedule → auto-publish

I'd test Sprout Social vs. Planable first.

• Choose Planable if humans reviewing/approving content is the core problem.
• Choose Sprout if the spreadsheet → bulk upload operation is the core problem.
• Choose Metricool if you want a lighter-weight option.
• Choose Agorapulse if client management, publishing, inbox, and reporting all need to live together.

One caveat: if by "calendars" you mean actual client marketing calendars beyond social posts (blogs, email, ads, campaigns, etc.), rather than social publishing calendars, I'd change the shortlist substantially.

If by “client-level calendars, approvals, and bulk scheduling via spreadsheets” you mean social-media/content scheduling for an agency, there are a few strong fits:

My shortlist

1. Agorapulse — probably the closest match

This is particularly well suited to an agency workflow. Its Shared Calendar lets clients see selected profiles/content without needing an Agorapulse account, and clients can approve, reject, comment, and request changes. support.agorapulse.com

The spreadsheet workflow is also unusually practical: you can prepare posts in Google Sheets/Excel, export CSV, and bulk-import them with dates, times, copy, links, media URLs, and labels. It supports up to 200 posts per CSV. support.agorapulse.com

It also has calendar-level bulk actions, including send selected posts for approval and approve all. support.agorapulse.com

2. Sprout Social — best if you want a more sophisticated enterprise workflow

Sprout supports external stakeholders reviewing content without logging into Sprout, plus flexible internal/external approval workflows. Its Publishing Calendar accepts CSV bulk imports of up to 350 messages, and the CSV can specify an approval workflow per row—very useful if your spreadsheet is effectively your production queue. sproutsocial.comhelp.socialpilot.co

The downside is likely cost/complexity if you're a smaller agency.

3. SocialPilot — best value if volume is the priority

SocialPilot can bulk import/schedule up to 500 posts from CSV and assign them to specific accounts, which makes a spreadsheet-driven production process straightforward. help.socialpilot.co

If I were designing the agency workflow

I'd lean toward:

Google Sheets → agency QA → bulk CSV import → client-specific calendar → client approval → automatic publishing

And I'd pick Agorapulse if client approval is the central requirement, Sprout if you need sophisticated enterprise permissions/workflows, and SocialPilot if high-volume spreadsheet scheduling and cost are the priorities.

If you tell me how many clients/accounts you manage and which networks (IG, FB, LinkedIn, TikTok, etc.), I can narrow this to the best 2–3 and compare their agency/client-permission models and pricing.

For an agency workflow with client-level calendars + approval flows + bulk scheduling from spreadsheets, you’re usually looking for a social media management platform (or marketing operations platform) with:

• separate client workspaces/calendars
• client approval permissions
• CSV/Excel bulk imports
• content queues and scheduling
• audit trails and collaboration

Good fits:

If your workflow looks like:

Spreadsheet → internal review → client approval → scheduled posts
I’d shortlist:

1. Planable — probably the closest match for agency/client collaboration. Each client can have their own workspace, calendar, approval stages, comments, and sign-offs.

2. Hootsuite — better if you have many clients, many social channels, and need enterprise-style permissions.

3. Sprout Social — best if reporting, client-facing analytics, and operational controls matter as much as scheduling.

4. Agorapulse — a strong middle ground for agencies that need approvals without enterprise pricing.

Spreadsheet workflow to look for

Make sure the tool supports a CSV with fields like:

Client
Date
Time
Channel
Caption
Asset URL
First Comment
Approval Status
Campaign

A lot of platforms support bulk upload, but the approval workflow is where they differ most.

If you’re an agency scheduling organic social, I’d lean Planable/Hootsuite/Sprout. If you’re scheduling ads, campaigns, email, blogs, and social together, you may want a marketing operations platform instead.

If you mean social-media/content scheduling for an agency, the workflow you described narrows the field quite a bit:

My shortlist

1. Sprout Social — strongest all-around agency workflow

Sprout explicitly supports client-specific groups and permissions, shared publishing calendars, and client approval workflows. Its bulk scheduler accepts CSVs and can assign an approval workflow to each imported row. sproutsocial.com

That makes a workflow like:

Google Sheet → CSV → bulk import → client approval → scheduled/published

quite natural.

One limitation: Sprout currently doesn't support bulk-approving multiple posts at once, so if clients routinely approve 30 posts in one click, that's worth testing. sproutsocial.comsupport.sproutsocial.com

Sprout Social for agencies

2. Hootsuite — best if you're more enterprise/large-team oriented

Hootsuite has account-level approval governance and, as of 2026, can record external approvals and approval notes in its audit trail/CSV exports. www.hootsuite.com

Hootsuite

3. Buffer — best if the spreadsheet is the source of truth

Buffer now has native CSV bulk upload specifically designed around turning spreadsheet content into scheduled posts. Its current documentation says bulk upload is available across Buffer plans. support.buffer.com

The tradeoff is that I'd choose Sprout/Hootsuite ahead of Buffer if formal client approval workflows are as important as scheduling.

Buffer

4. RecurPost — worth testing for a bulk-heavy agency

RecurPost combines client/brand workspaces, shareable calendars, approvals, and CSV bulk scheduling. recurpost.com

RecurPost

If I were designing your agency workflow

I'd test Sprout Social first, particularly if you have 10+ clients, multiple people involved in approvals, and reporting requirements.

The ideal workflow would be:

Client workspace → content calendar → client review/approval → approved posts → bulk scheduling → reporting

And I'd keep the spreadsheet as the content-production/import layer, rather than trying to make Google Sheets itself the approval system.

If your agency is very spreadsheet-driven (e.g. 50–500 posts imported at a time), I'd specifically compare Sprout vs RecurPost vs Buffer in a trial with one real client's calendar before committing.

Yes. If by “client-level calendars” you mean each client/brand gets its own workspace/calendar, with a workflow like draft → internal review → client approval → bulk schedule from Sheets/Excel → publish, there are several good fits.

My shortlist

1. Agorapulse — probably the closest match.
It explicitly targets agencies managing multiple clients, with collaboration, approval workflows, bulk actions and shared calendars. Its current CSV importer can take posts, media, links, labels and scheduling information, then either schedule them, review them, or save them as drafts. www.agorapulse.com

2. Sprout Social — strongest if reporting matters too.
Its bulk scheduler accepts CSV files and can import up to 350 messages at once. Importantly for an agency workflow, the CSV can specify an approval workflow per row, so you can have spreadsheet rows enter the appropriate approval process rather than simply publishing immediately. support.sproutsocial.com

3. Loomly — excellent if the calendar is the center of your operation.
Loomly explicitly supports one calendar per client/brand, with clients isolated from other clients' calendars. It also supports role-based permissions and multi-layer approval workflows. Its current CSV bulk upload lets you create/schedule multiple posts, although the import is limited to 60 rows per file. loomly.zendesk.com

If I were designing the agency workflow

I'd lean Agorapulse if the priority is:

Google Sheets → CSV → client calendar → internal QA → client approval → bulk scheduling → publishing

I'd choose Sprout instead if you also need sophisticated reporting/listening and have the budget for a more enterprise-oriented platform.

I'd choose Loomly if the biggest pain is getting clients to review and approve a monthly content calendar rather than high-volume spreadsheet ingestion.

One important distinction: “supports bulk scheduling” isn't the same as “supports a spreadsheet-driven approval workflow.” Sprout is particularly interesting because its CSV format can actually associate imported rows with an approval workflow. support.sproutsocial.com

If you tell me how many clients, which social networks (IG/TikTok/LinkedIn/etc.), and whether clients need to approve without logging in, I can narrow this to the best 2–3 and compare the agency pricing/workspace limits.

Yes. If by “agency workflow” you mean one agency managing multiple client brands, each with its own calendar, client approval process, and the ability to load a month’s worth of posts from Google Sheets/Excel, there are a few strong fits.

Best fits

My shortlist

1. Agorapulse — probably the closest match

Agorapulse now supports CSV bulk import where each row becomes a post, including copy, links, media URLs, dates and times. You can import to multiple social profiles and either schedule immediately, save as drafts, or review first. support.agorapulse.com

For an agency, the approval side is particularly relevant: it supports multi-step approval workflows, including internal and external/Shared Calendar users. You can also bulk-send existing scheduled posts for approval. support.agorapulse.comsupport.agorapulse.com

Typical workflow:

Google Sheet → CSV → Agorapulse client calendar → agency review → client approval → publish

2. Sprout Social — best if you want a more sophisticated agency platform

Sprout has client-specific profile groups/permissions, shared content calendars, approval workflows, and external stakeholders. Its bulk scheduler accepts CSV files and can create up to 350 messages in one import. sproutsocial.com

A particularly useful detail: the CSV can specify an approval workflow per row, so your spreadsheet can effectively tell Sprout which approval process each post should enter. sproutsocial.comsupport.sproutsocial.comsupport.agorapulse.com

That's attractive if you have, say:

• Client A → one-step approval
• Client B → marketing director → legal
• Client C → no approval

all being managed by the same agency.

3. Metricool — best value / spreadsheet-heavy workflow

Metricool is worth serious consideration if the spreadsheet is central to your process. It supports CSV batch scheduling, multiple brands, calendar views, and approval workflows. help.metricool.com

Its approval system can send posts to clients/external reviewers by email, and clients can approve or reject without necessarily having a Metricool account. help.metricool.com

It also lets you share a read-only calendar with clients, which is useful if clients mainly need visibility rather than full access. help.metricool.com

If your agency's workflow is specifically:

“Our team lives in Google Sheets. We create 50–200 posts per client, upload them, the client reviews them on a calendar, makes comments/edits, approves them, and then they're automatically published.”

I'd rank them:

🥇 Agorapulse — best overall match
🥈 Sprout Social — best enterprise/complex approval setup
🥉 Metricool — best cost-conscious spreadsheet-centric option
4. Planable — best if collaborative client review is more important than bulk CSV operations

One important distinction: “bulk scheduling” and “bulk scheduling into an approval workflow” aren't the same feature. Sprout and Agorapulse are especially strong here; Agorapulse explicitly supports bulk sending scheduled posts for approval, while Sprout lets you assign an approval workflow in the CSV itself. sproutsocial.comsupport.sproutsocial.comsupport.agorapulse.com

If you tell me roughly how many clients, posts/client/month, and whether clients need to edit copy or only approve/reject, I can narrow this to the best 2–3 and compare their likely pricing/plan requirements.

If your agency's workflow is:

1. Build content in a spreadsheet (Google Sheets/Excel)
2. Get client approval
3. Schedule hundreds of posts
4. Keep each client's calendar separate

then there are a handful of platforms built specifically for that.

If spreadsheets are central to your workflow

I'd narrow it to:

RecurPost

• Imports directly from CSV/Excel
• Client workspaces
• Approval workflow
• Visual calendar
• Good if you already plan everything in Sheets recurpost.com

SocialPilot

• One of the better agency-oriented products
• Client access without giving full permissions
• Bulk scheduling
• White-label reporting
• Competitive pricing for many client accounts www.techradar.com

Agorapulse

• More expensive
• Strong collaboration
• Robust approvals
• Bulk publishing
• Excellent reporting if clients expect monthly reports www.techradar.com

Enterprise agencies

If you're managing 50–500 brands, there are newer platforms emphasizing bulk operations:

• SkedCast focuses on spreadsheet imports, approvals, and large-scale multi-client scheduling. skedcast.com

A workflow many agencies use

Many agencies don't rely on a single tool. A common stack is:

• Google Sheets → content planning
• Client approval (either in Sheets or the scheduling platform)
• CSV import into the scheduler
• Visual calendar for final review
• Auto-publish

Some agencies even automate this with Google Sheets and tools like n8n so that changing a row's status to "Approved" triggers scheduling automatically. Community discussions describe this approach as a way to reduce manual copy-and-paste and simplify client reviews. www.reddit.com

For most agencies with 10–100 clients, my shortlist would be:

• Best overall: Agorapulse
• Best value: SocialPilot
• Best if everything starts in spreadsheets: RecurPost
• Best for high-volume agency operations: SkedCast

If you can share approximately how many clients you manage (e.g. 20, 100, or 500+) and which social networks you publish to, I can narrow the recommendations further.

If you're running an agency with multiple clients and your core requirements are:

• Client-specific content calendars
• Client approval workflows
• Bulk scheduling from spreadsheets (CSV/Excel)
• Multi-account social publishing

then a few platforms stand out.

Best value: SocialPilot

Good if you manage dozens of clients.

Pros:

• Separate workspaces per client
• Share approval links without requiring client logins
• Bulk upload hundreds of posts via CSV
• Role-based permissions
• Generally lower cost than enterprise tools

Potential drawback:

• Analytics are solid but not as deep as premium enterprise platforms.

Best approval process: Sendible

Many agencies choose it because the client review process is smooth.

Highlights:

• Draft → internal review → client approval
• Multiple brands and workspaces
• CSV bulk imports
• White-label reporting
• Easy content libraries

Best editorial experience: Loomly

If clients frequently request edits before publishing:

• Beautiful calendar interface
• Comment directly on posts
• Approval history
• CSV imports
• Content suggestions

It's especially strong for agencies where marketing managers and clients collaborate closely.

Enterprise choice: Sprout Social

If budget isn't a major concern:

• Sophisticated approval chains
• Client workspaces
• Asset management
• Excellent reporting
• Team governance

The tradeoff is significantly higher pricing.

If your content starts in Excel or Google Sheets

Many agencies use this workflow:

1. Plan content in Google Sheets or Excel.
2. Export as CSV.
3. Import into the scheduling platform.
4. Route posts for client approval.
5. Publish automatically after approval.

Platforms that handle this particularly well include:

• SocialPilot
• Sendible
• Hootsuite

My recommendation by agency size

• 1–20 clients: SocialPilot offers one of the strongest combinations of features and value.
• 20–100 clients: Sendible provides a polished approval workflow and scales well for agency operations.
• 100+ brands or enterprise clients: Sprout Social is a strong fit if advanced governance and analytics justify the higher cost.

If you're also looking to automate content creation from spreadsheets or AI-generated drafts, there are additional platforms that integrate with tools like Google Sheets, Airtable, or Zapier, which can reduce manual work even further.

If you're running a marketing or social media agency and need client-level calendars, approval workflows, and bulk scheduling from spreadsheets, there are several strong options. The best choice depends on how much you prioritize approvals, scale, and integrations.

Top recommendations

1. Agorapulse

• Separate workspaces for clients
• Internal and client approval workflows
• Shared content calendars
• Bulk upload from CSV
• Role-based permissions

Spreadsheet workflow

Most agency-oriented platforms support a process like this:

1. Plan content in Google Sheets or Excel.
2. Export as CSV.
3. Upload to the scheduler.
4. Review imported posts in the calendar.
5. Route them through internal approval.
6. Send to the client for approval (if enabled).
7. Publish automatically.

Typical CSV columns include:

• Date
• Time
• Client/account
• Platform
• Caption
• Image/video URL
• First comment (where supported)
• Hashtags
• Campaign tag

If you manage 50–500 clients

Look for features such as:

• Separate calendars per client
• Folder/workspace organization
• Multi-step approvals
• Content libraries
• Bulk CSV imports
• Reusable post templates
• Asset management
• Team permissions
• Approval audit history

My shortlist

• Best overall agency platform: Agorapulse
• Best value: SocialPilot
• Best white-label experience: Sendible
• Best budget-friendly option: Metricool

If your workflow also includes AI content generation, automated client onboarding, or approval via email rather than requiring clients to log in, I can narrow the recommendations further based on those requirements.

Yes. Those three requirements—client-level calendars, approval workflows, and bulk scheduling from spreadsheets—are supported by several agency-focused social media management platforms.

Here's how the strongest options compare:

If spreadsheets are central to your workflow

The most spreadsheet-friendly platforms are:

• RecurPost
  • Import CSV or Excel directly.
  • Map spreadsheet columns to platforms.
  • Preview everything before publishing.
  • Designed around agencies uploading large batches of posts. recurpost.comrecurpost.com

• SocialPilot
  • CSV bulk scheduling.
  • Client approval flows.
  • Good value if you're managing dozens of clients rather than hundreds. www.techradar.comwww.techradar.comwww.techradar.com

If client approvals are the bottleneck

Look for:

• client guest access
• approval before publish
• comments on drafts
• approval history/audit trail
• separate permissions per client

Sendible, Agorapulse, and Zoho Social all provide mature approval workflows aimed at agencies. www.techradar.com

Typical agency workflow

A common setup looks like:

1. Plan content in Google Sheets or Excel.
2. Bulk import the spreadsheet.
3. Automatically assign posts to each client calendar.
4. Notify the client for review.
5. Client approves or requests edits.
6. Approved posts publish automatically on schedule.

That eliminates most copy-and-paste work while keeping each client's content separate.

My recommendation

• 5–30 clients: SocialPilot or Sendible
• 30–100 clients: Agorapulse or Sendible
• Spreadsheet-first operation: RecurPost
• Already invested in Zoho: Zoho Social Agency

If you're managing 50+ clients or want approvals tied directly to a Google Sheet (rather than importing a CSV each time), it may also be worth building a custom workflow with Google Sheets plus automation tools like n8n or Make, feeding into a scheduler. That approach gives you a single spreadsheet as the source of truth while still using a commercial publishing platform for approvals and posting.

If you're managing multiple client accounts, the workflow you described—client-specific calendars + approval workflows + bulk scheduling from spreadsheets—is well supported by several social media management platforms. The best choice depends on how many clients you manage and how important approvals versus automation are.

Here's a comparison:
