I have Excel file in binary format in a local folder (see this link: Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.). When I want to save (save as) this file, it keeps crashing. I have searched the internet and tried all the remedies mentioned in it.( open and repair, changing the file name, changing the file extension, opening Excel in safe mode and …) with no success. Can you guide me on this issue?
