App corrupts Excel files, preventing opening on other normally compatible software
Opening, or in the case of password-protected files merely trying to open, an XLSX file in Excel for Android modifies the file. Permission is not requested and autosave is disabled, but file size is increased by roughly 30 % and the file then appears as corrupted to desktop Excel and other software such as Google Sheets.
Sample files, both original and corrupted (-and), enclosed. Password is "password".

I have absolutely no idea what you are talking about! My Excel file worked....then a month ago it went nuts...not working compatible. Why? It is an Excel calendar. Every year I have the date changed and I can type in our schedule. It Saves eventually - but always says (Not Responding) then finally responds and saves. Right now I cannot save the calendar file, I cannot exit the excel
file...I cannot change one item in the file. Now what do I to keep my yearly 2019 file with my info. typed in from January 2019 thru 12-31-2019. It just contains information, Clean Cat water fountains, apply flea medicine, some appointments, dates were ill …. I mean no exciting information for anyone else's use... but for us. I scotch each month in our bathroom. Important reminders for us, but of no value to any one else! I have been making these calendars since 2013, first in MS Word and now in MS Excel.
