Hi,
I am looking for a solution that someone may have, regarding decripting xlsx files.
Maybe Anton Scheffer has an idea?
When an xlsx is workbook protected, and you create it with, or edit/save with... Office 2007, then the xlsx file gets encrypted, and the signature for that file changes to the same as an .xls file.
In any case, reading it as an .xls or reading it as an .xlsx file won't work.
First needs to be decrypted.
When this happens with Office 2010, it does it differently, and in any case, it can be read perfectly with an xlsx reader.
Does anyone have a way to decrypt in pl/sql? Or some sort of instructions that are clear to someone that is not very "smart" (I mean, ME) on low level programming (I mean, using raw instructions) in Pl/sql?
Thanks!
