Can't open password protected xlsx files in iOS 14.2

Hi to everyone,


since the update to iOS14.2 I can't open password protected xlsx Excel sheets in mail app anymore that I am receiving by email. I always get the note "Decryption failed (null)."

(Opening the file with Numbers app works fine)


Does anybody has the same problem or even a better a solution for that? :-)

The appropriate procedure for working around this issue has been posted in this thread several times.


No need to copy the file,


1)Make sure the excel app is installed


2) Simply ignore the initial request for the doc password and click the box with the up arrow in the top right of your screen


3) Select “open in” or “open with” and choose excel.


4) excel will ask for the pw and viola. You’re in.

Thank you but that requires having the appropriate app installed which wasn't a requirement before Apple broke it. Before this last iOS update we could open password protected files without having the file program (MS Word, MS Excel, etc.) installed. What you provided seems to be the work-around, we're all seeking a permanent fix back to how it was working a couple of weeks ago.
