Definitely require for Power BI refresh. Absoletly need. I have an excel spreadsheet generated from SSRS and apparently cannot be in xlsx format, so refresh doesn't work...
Have the same issue myself. MS Flow removes the attachment from a daily email and places it in SharePoint. Urgently need to convert XLS to XLSX so that Power BI can perform it's scheduled refresh daily without any manual intervention.
Any chance this has been implemented? I have the same issue. Perhaps convert from XLS to CSV would even help. I actually believe this is possible, but not sure how.
Seems like this is a pretty common issue that I would hope is being looked at. Either Power Bi needs to allow xls files or Flow needs to have a recipe to convert xls files to xlsx files.
Agree! Would be great if we could open and save an excel file as an alternative format. In particular I'm after the ability to open an excel .xls and save as a newer .xlsx format using Microsoft Flow. Vote Vote Vote! 🙂
