Excel workbook remains corrupted after trying all repair options

Thanks a lot. I will use the last version from July. Have a blessed week.

Sorry - not for that file :'(
If it was saved on onedrive/sharepoint there may be a possibility to go back to a previous version (You'ld probably already tested that in case it was possible).
Possibly but unlikely a completely different program like BI appllications QlikView or Qlik Sense could read only the data and don't bother about crashed conditional formatting or similar. Qlik is just one possibility. microsoft Power BI is probably too close to Excel but may be worth trying. Also other BI programs that have the possibility to load directly from Excel files.

I have been in the same situation soo many times and started to use F12 (Save as) to add a timestamp to the file like every ten minutes.
Some times I also add a note on what I am working on at the moment, or what I am about to start to do so I have a version to go back to in case I would like to.

Using a notation like YYMMDD the files will be sortable also by names.

Hi,
I've tried all. No one worked, unfortunately. Same msg, File corrupted.
Any other suggestion?

Try to import the data into a new file using Data: get Data: From File and see if you get your data back.
Then, consider the datas sensitiveness since I suggest try by sending it to someone elses server. If data is not too secret;
- Have you tried to open with Excel 365 "in the cloud"
- Also, try to open the file with Google Sheets - (always cloud).
