Fix an A/B Test XLSX Export Error

Explains how to fix an XLSX export error caused by special characters in an A/B test's name.

Use this guide to fix an error that occurs when downloading an XLSX export from a running A/B test so you can access your test results without interruption.

What causes this error

If you see an error page when trying to export A/B test results as an XLSX file, the most likely cause is a special character in the test name — for example +, &, or %.

Special characters in the test name interfere with the export download. This is a known product limitation. Renaming the test to remove the special character resolves the issue immediately.

How to fix it

1. Go to Popups and open the A/B Tests tab
2. Open the affected test
3. Rename the test to remove any special characters. For example, replace Summer + Fall with Summer and Fall
4. Click Save
5. Retry the XLSX export — the file should now download successfully

Notes and best practices

• Avoid: Using special characters such as +, &, or % in A/B test names. These can cause export errors
• Recommended: Use plain words or hyphens instead (e.g., Summer and Fall, Summer-Fall)
