Import and Export Limits in ClickUp

When you move work in or out of ClickUp using the public API, it is essential to understand the current import and export limitations. This guide explains the practical constraints you must follow so that large data migrations, backups, and integrations run reliably and predictably.

The information below is based on the official developer documentation and focuses on how to structure requests, respect system limits, and design robust workflows for high‑volume workspaces.

Overview of ClickUp import and export behavior

The import and export logic in ClickUp is optimized for stability, data integrity, and protection against overload. Rather than hard global caps, the platform applies a mix of size thresholds, batching rules, and timeout handling. Understanding these behaviors helps you avoid failed imports, partial exports, or unexpected throttling.

At a high level, these constraints apply to:

• How ClickUp handles large JSON payloads.
• How attachments are uploaded, stored, and referenced.
• How task counts and hierarchy depth influence request design.
• How long-running import and export jobs are monitored.

Whenever you design a migration tool or integration, budget extra time for testing your data structure and volume against these limits.

Preparing data for ClickUp imports

Before importing, validate and normalize your data so it matches the task, list, and space structure supported by ClickUp. This preparation minimizes errors and makes troubleshooting far easier.

ClickUp data structure best practices

When modeling incoming data, map your hierarchy to the standard workspace structure. Typical levels you will work with include:

• Workspace
• Space
• Folder
• List
• Task and subtasks

Keep hierarchies reasonably shallow. Deeply nested trees create heavier payloads and may increase the chance that imports reach internal processing limits or time out.

File size and attachment planning for ClickUp

Attachments are often the biggest source of problems in bulk imports. Plan for the following constraints when working with files:

• Use modest file sizes wherever possible instead of a few extremely large assets.
• Avoid bundling large binary data directly into your main JSON payloads.
• Prefer linking or staged uploads if your integration design allows it.

If you are migrating a legacy system with very large files, consider archiving oversized assets outside of ClickUp and storing references instead of full attachments.

How to import data into ClickUp safely

To keep imports reliable, design your process as a sequence of small, validated operations rather than one all‑or‑nothing bulk request.

Step 1: Audit your source before importing into ClickUp

1. Export a representative sample of your existing data.
2. Check for malformed fields, missing IDs, and invalid dates.
3. Normalize user references, custom fields, and status names to match your target ClickUp workspace.

Fixing these issues in advance prevents repeated failures and reduces the number of retries you need to perform.

Step 2: Chunk your import requests

Instead of sending all tasks in a single call, break them into batches based on list, folder, or logical groupings. For example:

• Import 100–500 tasks per request, depending on payload size.
• Split large attachments into multiple uploads.
• Create parent tasks first, then import subtasks in follow‑up calls.

Batched imports are easier to resume and less likely to hit processing timeouts in ClickUp.

Step 3: Monitor responses and handle ClickUp errors

Your integration should watch for API status codes and error messages, then respond intelligently. A resilient importer will:

• Log IDs of any records that fail.
• Retry transient errors using incremental backoff.
• Stop and alert on repeated failures with the same payload.

This approach lets you diagnose whether issues are related to volume, structure, or specific records.

Exporting data from ClickUp

Exports must also account for pagination and potential limits on result sizes. Planning your export workflow makes large workspace backups and reporting pipelines more predictable.

Plan ClickUp exports with pagination

When exporting tasks, comments, or other entities, always assume partial result sets. Common best practices include:

• Request items in pages, using limit and offset or cursor parameters where available.
• Store pagination tokens or offsets between calls.
• Verify that each page is fully processed before requesting the next.

This ensures that exports are resumable and that network or timeout problems do not corrupt your data snapshot.

Control payload size in ClickUp exports

If you export a combination of tasks, subtasks, and attachments, the response payload can become large. To minimize issues:

• Filter to just the fields you truly need, if the endpoint supports it.
• Export related entities (tasks, comments, custom fields) in separate passes.
• Write each page to persistent storage immediately instead of keeping everything in memory.

These measures make your export tool more stable and easier to operate against big workspaces in ClickUp.

Handling long-running operations in ClickUp

Large imports and exports can take significant time. Design your tooling so that long‑running operations are transparent and recoverable.

Track job progress and completion

Implement logging and monitoring so you can see:

• When a bulk import or export started.
• How many records have been processed so far.
• Which batches succeeded or failed.

This visibility lets you identify patterns, such as a specific list or attachment type that repeatedly causes failures in ClickUp.

Design ClickUp workflows for resilience

Align your workflows with these resilience principles:

• Idempotency: ensure that re-running an import for the same batch does not create duplicates.
• Checkpointing: store progress markers so you can resume from the last successful batch.
• Isolation: separate critical business data from optional metadata during migration.

Following these guidelines reduces risk if your ClickUp operations are interrupted by network outages or configuration errors.

Best practices for large-scale ClickUp migrations

Migrating entire workspaces or large projects requires additional planning and testing to stay within system limitations.

Stage and test your ClickUp migration

Before you move your production workspace, perform a complete rehearsal:

1. Create a staging workspace in ClickUp.
2. Run a full end‑to‑end import using a copy of your source data.
3. Validate counts, hierarchies, and attachments after the test run.

This rehearsal reveals any bottlenecks or hidden constraints long before your real cutover.

Coordinate cutover and validation

For production migrations, coordinate with stakeholders and define clear checkpoints:

• Freeze changes in the source system during the final export window.
• Run the import into ClickUp during a low‑usage period.
• Validate critical projects, lists, and tasks with key users before reopening the system.

Document any known limitations and agreed‑upon workarounds so everyone understands what to expect during and after the migration.
