Well known and really anoying bug. It seems to generate when using the VBA editor and deleting some worksheet that is referenced by some formula.
I have resolved (most of the times) by completely removing the vba project using this procedure:
- Create a backup copy of the file (from file explorer)
- Change file extension from .xlsm to .zip
- Open the .zip file and locate the file
/xl/vbaProject.bin
- Remove this file
- Change the file extension back to .xlsm
- Open normally the modified file. It should not show the error and save without problems
Obviously in this way you will loose all the VBA macros in the Workbook, so you have to re-import them from the last (hopefully) working version of your file.
Is there any update? Please remember to share us with solution when you solve this issue, and accept you reply as an answer.
Yeah, this error caused me half day of work. i've tried the effort of copying it onto a plain new excel worksheet, but it just keeps spinning and does not let me save or even do anything in the new worksheet. I was able to save it as pdf, since it is something I work on top of other people's worksheet, I will be relying on the next worksheet I receive would not have the same issue.
Hope this helps a little?
Best of luck!
