When using VNQM in Observability Self-Hosted, and specifically looking at the VOIP Call Data, you have the option to export the call data to excel. This auto chooses the Microsoft Excel 97-2003 file format. I would like to request that the file format here is optional, so I can select a newer file format, or the default file format be upgraded to Excel Workbook (xlsx).
Currently due to 93-2007 excel xls being legacy and outdated, most corporate security policies are adding it to the blocked file list in Excel.
