### Description: Test description updates

When attempting to export the audit log as a CSV or XLSX file, the file downloads successfully. However, upon opening, the file shows an error indicating it is either corrupted or not in a valid format. As a result, users are unable to access the exported data.

### Steps to Reproduce:

1. Log in to the application.
2. Navigate to the Audit Log section.
3. Click on Export to CSV or Export to XLSX.
4. Allow the file to download.
5. Attempt to open the file using Excel or another spreadsheet tool.

### Expected Result:

The downloaded CSV/XLSX file should open correctly and display the audit log data in a proper, readable format.

Start by reproducing the Audit Log export flow described in the issue, testing both CSV and XLSX downloads and opening each with a spreadsheet tool. Trace the export entry point and inspect the generated files; done means both formats download and open successfully with readable audit log data.
