I have a powerapp that's connected to an excel file stored on OneDrive. When trying to open the excel file online (to add a few columns) I'm getting:
Couldn't Open the Workbook
We're sorry, we couldn't open your workbook. It's possibly corrupt or using a file format that's not supported.
The app is working fine. Why this error and how can I edit the file?
Could you please share more details about the Excel file, specially for the file format?
Any changes has been made for this Excel file? It might be corrupted.
Please take a try with the steps mentioned in the following link, see if that would help:
Regards,
Michael
