Excel Password Removal / Hack Protected XLS File

Posted on 2013-02-05
Last Modified: 2013-02-26
I recently had a client pass away. He kept a 2003 Excel document with a list of passwords on it. The problem is the document is password protected and his company needs these passwords.  I've attempted a brute-force attack and it failed. Is there a way to simply extract the data or remove the password with something like a hex editor?

There are commercial products available to do this for you.  If you type 'Excel passsword remover' into Google, you'll get a number of links, both reputable and otherwise.
