i don't know if this is relevant section to post this but im taking my chances.
I need to bypass the password for .xlsx file saved using office 2010. This is very important doc (contains classified important stuffs ) so i saved it using a password but now i forgot the password
I can't use brute-force on it, as i know its a very strong password and it will take years to find my password in that file.
I tried VBA method but those are meant for pre-2007 saved excel files, tried hex-edir but not able to find the DPB stings
