I very often have to work with Excel of different versions, but this is the problem I face for the first time, so I hope for your help. Recently, I had to send important calculations to my engineer. But I could not do it because of a serious failure in the system. When I tried to open the file again, there was an error - Microsoft Excel has encountered a problem and needs to close. I tried to open the same file through another PC, but the problem did not resolve, it seems, the file is corrupted. If I can not restore the file before it is noticed at work, I will have problems.
