# Generate a test set for Test Workbench
<a name="test-sets"></a>

You can create a test set to evaluate the performance of your bot. Generate a test set by uploading a test set that is in a CSV file format or by generating a test set from [ conversation logs](https://docs.aws.amazon.com/lexv2/latest/dg/conversation-logs.html). The test set can contain audio or text input.

If a test set creates validation errors, remove the test set and replace it with another list of test set data, or edit the data in the CSV file by using a spreadsheet editing program.
