I have tried to convert to .xlsx then I couldn't even see the data I tried to zip and send then unzip same warning popsup

Answer 1

My guess as to what is going on is that the incoming Excel file is still basically a Linux file, but MS Office, being flexible, is allowing you to open it. For a one time fix, try the following steps from Windows Excel:

• Open the Linux Excel file ( some_file.xlsx )
• Save as another file name ( some_new_file.xlsx )
• Close Excel
• Delete some_file.xlsx and rename some_new_file.xlsx to some_file.xlsx

Now try opening the file again, and hopefully the error message will have gone away.
