I have this problem.
When user tries to save an Excel file, Excel shows an error message:
"Errors where detected while saving April.xlsx. Microsoft Excel may be able to save the file by removing or repairing some features. To make the repairs in a new file, click Continue. To cancel saving the file, click Cancel."
Then the user click Continue button and try to save it again but the repair obviously failed because a new error message appears - that there are too many formula errors.
I tried to copy data to the new Excel document as many sites recommended but it didn't help.
Note: This Excel file was copied and rewritten many many times.
Thank you for any advice.
