#Excel 2016 xlsx cannot open .xlsx files windows

I still think that this thing is related to One Drive.ДЇinally, I tried to attach one of the files and received the error message: Also, the same problem occurs with all spreadsheets restored. It's frustrating because I can see that the size of the recovered file is a little bigger than the outdated file, what is coherent. I've tried all solutions posted here, and also all solutions proposed by Microsoft, but I had no success. I deleted the original One Drive folder, and the system asked for a complete deletion, because the folder was too big.ДЄfter knowing that some of my spreadsheets were outdate, I recovered them using third party software, but Excel doesn't open them, the message is the same in this post. Good my case, the same problem occured after I moved my One Drive folder to another disk, because the original location had no more space.ДЄfter moving, the files in the new place became outdated, probably because local files were not synchronized with the cloud.

If you donвЂ™t have permission to open the Excel file, it will display the error 'Excel cannot open the file because the file format or file extension is not valid.' I have tested this on my Windows 10. If you have tried all possible methods to repair your Excel file but none of them work, then maybe your Excel file is not corrupted, but you just donвЂ™t have permission to open it on your system.
