I have 2 files in excel that are .xlsx format. They were both corrupted somehow I don't know and both are so far unrecoverable. The things I have tried so far: the error is: Excel cannot open the file 'blah.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

Changing file format to xls or xlsm . Using excel's open and repair method, including the extract data method The ""Recovery Toolbox"" program Microsoft recommended options: Set the calculation option to manual Use external references on the corrupted workbook

I've also tried the suggested to rename the file as .zip and then open it, but it doesn't let me open it.

I also paid for and downloaded SysInfo tools repair but I'm afraid that may be a scam as they don't let you see the output until you pay, then once you pay, they are not sending me the authorization code and the live chat doesn't work.

In any case, running out of money and luck to get this corruption fixed. Any other, different ideas as to how to repair? One of the files is attached here.

You should now be able to attach a file.

Let me ask you a question. Which application SW are you using to open the file? If you use EXCEL, you better ask somewhere where there are specialists for EXCEL. This forum supports Calc, a part of LibreOffice.
