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.

Actually, you should be talking in O notation. These days, anything under O(^n) is solvable in a reasonable time for a price.

Find someone who knows the password, and remove their fingernails.
The only person who knows it died, hence why I'm attempting to crack it.
It is an excel spreadsheet that my father used to keep track of all his other passwords, unfortunately it is password protected. He died and I'd really like to know whats inside.

Can you elaborate? Meaning I could go out and spends lots of money to build a Beowulf cluster and solve it in a few days?

Actually, I think you shouldn't do it. He probably password protected it for a reason.
Congratulations on your father's death!
He would be very proud of you.

Are you in a hurry to get to what's inside? When I was your age, even 8 character passwords would take over a century. Kids these days...

It's strange just how often that is the solution

well, he had to put the password to excel on something other than the excel that has all his passwords in it.. seems kind of weird anyway, ive never heard of anyone keeping all their passwords in a damn text file..

People design websites in fucking HTML tables because they like the "layout control" they get.
You can see real examples of this all over the internet. Along with 300KB+ sized autogenerated pages.

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.

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.
