We don't have an official import from the Teamwork feature. We do have an awesome CSV Import feature that allows you to bring all your data to ClickUp! Here's how it works:
If Teamwork states that they can only export your data via a MySQL file, you can proceed here to convert that into a CSV.
Use our CSV Import feature to bring this into ClickUp!
Tips for after the Import
Once the import is complete, you can use our Bulk Action Toolbar to quickly maneuver your tasks, add assignees in bulk, and more.
