Limits and quotas
This page lists the limits that apply when you work in Mammoth. Other pages mention a limit where it matters and link here. Some limits are fixed for every workspace. Others are set by your plan.
Data import
| Limit | Value | Applies to |
|---|---|---|
| Size per upload request | 50 MB | Every plan. A folder upload counts as one request. See Uploading files. |
| Files per upload | 1,000 | Uploading files in one go. Files go up in groups of 50, with a 30-second pause between groups. |
| Rows when generating a dataset with AI | 1 to 500 | The User defined row count in Generate with AI. See Generate with AI. |
| PDF pages | 2,000 | PDF extraction. See PDF extraction. |
The 50 MB limit is the same on every plan. If an upload is larger, split it or reduce it before uploading, or import it from a URL or connector.
Pasting data from the clipboard has no documented row limit. If the browser cannot hand over the pasted content, Mammoth shows "Content too large to paste. Use the file upload option instead." Upload the file instead.
Transform and AI
| Limit | Value | Applies to |
|---|---|---|
| Rows processed by Generative AI | 50,000 | The first 50,000 rows of the view. |
| Characters per Generative AI answer cell | 300 | A longer answer fails with an excessive data generated error. |
| Context columns for Generative AI | 20 | Selecting more than 20 columns shows "Maximum 20 columns can be selected." |
| Rows in a Generative AI preview | 10 | The Preview button. |
| Join result size | 100,000 rows and 5 times the larger input | Mammoth blocks a join whose predicted result is over 100,000 rows and more than 5 times the row count of the larger of the two views. See Unify. |
Generative AI runs use the external API key your workspace owns, so they do not count against a plan allowance. See Generative AI.
Export and email
| Limit | Value | Applies to |
|---|---|---|
| Rows in an XLSX download | 50,000 | Views over this size show "XLSX download is not available for views over 50,000 rows." Download CSV instead. See Download options. |
| Rows attached to a Messaging email | 100,000 | The combined row count of all attached views. See Messaging. |
Schedules
The shortest interval you can set depends on your plan's refresh frequency.
| Unit | Choices in the scheduler |
|---|---|
| Minutes | 5, 10, and so on up to 55 in steps of 5 |
| Hours | 1 to 23. When your plan's refresh floor is hourly, the minimum is 3. |
| Days | 1 to 6 |
| Weeks | 1 to 3 |
| Months | The 1st to the 31st |
| Years | 1 to 5 |
- Messaging schedules do not offer the minute option.
- Data Consolidation has no schedule. It runs when a file lands in the source folder.
- Your plan sets the shortest interval you can schedule (see the refresh frequency row in Plan allowances): Free cannot schedule runs, Starter schedules weekly or less often, Team daily or less often, and Pro every 3 hours or less often. No self-serve plan offers an interval of 1 hour. See Scheduling.

Trash and activity history
| Limit | Value |
|---|---|

API rate limits
Mammoth limits API requests per minute for each user session, or per IP address for unauthenticated requests.
| Method | Requests per minute |
|---|---|
| GET | 600 |
| POST | 300 |
| PATCH | 60 |
| DELETE | 60 |
| Other methods | 600 |
Going over a limit returns a 429 response with "Rate limit exceeded" and a retry_after of 60 seconds. See API errors for handling details.
