1st recommendation: do a redundant backup now, i.e., 2 copies in removable media
2nd one: copy a few files and test them in other computers and/or upload them here
3nd one: uninstall and reinstall Excel
4th: ran an online antivirus, then update your AV definitions
5th: same for malware detectors (i.e., Spy Bot Search & Destroy)
6th: general backup
7th: format disks and reinstall Windows and software
8th: use professional software for fixing corrupted excel files Recovery Toolbox for Excel https://excel.recoverytoolbox.com/

Hi

This is the forum to discuss questions about Microsoft Excel develop (VBA, automation). For your question is about Excel features, I recommend post the question to the TechNet forum for Excel

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us.

Thank you for your understanding.
