Hi there,

I have been looking for Flow solutions that aren't paid but can't find one. I have found some tips on Powershell for converting XLS to XLSX but that is all for local directories. I wanted to have a process run automatically when a folder is populated with files on Sharepoint.

Is there a script anyone can share? I am no programmer but can understand the basics of powershell and basically am not sure how to use powershell with Sharepoint libraries and folders.

    Best way to do it, is use Onedrive to link sharepoint to your own personal documents then write a powershell script that converts any new file added. Powershell wont need to be open or pc on, so its quite helpful

    Per my test, converting .xlx files to .xlxs files automatically in the SharePoint folder is not available.

    As a workaround, you should change files extension in the client application manually. File -> Save as -> Choose .xlx type -> Save.
