Need to recover a file, how?

Question

excel

Please tell me how can I restore the .xlsm file? The fact is that the other day one of these files, when opened, reported that it was damaged, and I just can’t just close my eyes to it, since it contains a lot of data about each of my employees. Help out!

Answer 1

Does 7-zip even open it?

Answer 2

In principle, you can even just try to send this file to yourself by mail. Many browsers have built-in editors for opening different types of files, and sometimes they do even better than MSoffice.
