Details: "The input couldn't be recognized as a valid Excel document."

[Alexandrini]

Have been trying to upload the workbook but got this error "The input couldn't be recognized as a valid Excel document." The database is big with different tabs. Tryed to delete all tabs but one and it didn't help either. The only thing that works if I copy the data from the tab to another file but I can't do it with all the tabs. Is it possible to resolve the issue?

Thanks!

I resolved the issue by copying to a new file. It seems that the problem occured when I  copied a tab from other file. There was nothing wrong with that tab. It worked Ok in the initial file. But simple deleting of the tab from the file didn't help. Just full recreation.

@Alexandrini

Are the data in your workbook formatted as table or they are just range?

If they are table, please try to convert to range and have a try again.

If issue still persists, could you please provide your excel file to me since I cannot repro this issue locally? You can share the file through online file service or send through PM.
