Cracking Excel 2000 Passwords?

So, I have a problem.

I need to crack an Excel 2000 spreadsheet with file password protection. The password could contains all letters, numbers, and symbols, and be up to 15 characters long. All programs I've tried tell me it takes months to crack. I believe this since there are literally trillions of combinations in a character set this large.

What do I do? I need the information inside the file.

Also, waiting months is not really an option.

Old-school accountants are particularly bad for this. They learn Excel for their job and use it as the hammer for every other nail. I've seen 100-page documents written in Excel, complete with manual page numbering on every 'page' - and when they want to add a paragraph somewhere in the middle they cut+paste cells all the way down to the end. Truly awful.

Scour his hard disk for previously unencrypted copies of this file. It may be in the free or slack space of the disk so you'll need to use something like WinHex to find it.

Install Open Office, problem solved.

He obviously knew what he was doing as he didn't use Excel's shit, easily crackable encryption. That implies that he really really didn't want anyone accessing his stuff, including YOU.
