Excel writes when opening a document: "The file is damaged, so it cannot be opened." How to fix?

Question

excel

How can this problem be corrected? I tried to restore through Excel itself, it does not work. What other options are there?

Answer 1

Starting from "manually fix 1 byte in the header" and ending with "no way", because you did not specify the degree of damage to the file.

Answer 2

You can try to open through another office suite, such as OpenOffice. You can also try to see what happens here: https://onlinefilerepair.com/ru/excel-repair-onlin...
