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.

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.

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.
