convert XLS to XLSX



Is there a way to convert XLS to XLSX using flow? 


I do not have a premium account so I wont be able to use UI flow.

If it truly is XLS, and not just XLSX with an XLS extension, then its the older binary format.  To convert that you would need a running copy of Office or something with the Office API.  There used to be 3rd party web services that could do it, but that would also be a cost and require a custom connector which is premium.  I don't think there is any way to do it with just a standard Office 365 Power Apps license.
