One of these should work

Are you finding that Microsoft Excel won’t open a file on your computer? If so, your file may be corrupted or there may be a problem with your Excel app, Windows or Mac system. We’ll show you how to work around this issue so you can view your spreadsheet data.

The main reason why a Microsoft Excel file won’t open can be that the file is corrupted. However, there can be other causes as well, such as the wrong file extension, an external device that is not responding, a problematic Excel add-in, and more.

If you have multiple spreadsheet programs installed on your computer, chances are you're using an app other than Excel to open your file.
