I forgot the password for my excel file.
I have tried some programs such as
Accent Excel password recovery,
advance office password recovery.
Neither did work.

Well, your options are to either remember the password or find a recovery
program that works for you. No guarantees - if you picked a really good
password it will be tough to break it.

http://www.excelpasswordrecovery.net/ just click this link and recover excel
file password........
I'd like to know the theory. If the password could be broken, why MS not
release a fix?

If the file has a password, I reckon that password must be included in the
file. If it's in the file, it can be found. If it can be found ...

:)

Anyone know if that's how it works ? :)

If you don't want people to see a spreadsheet, don't send it to them or
allow them access to it. That's security. :)

Those MS guys can't be so simple to play with :)

I guess it be something using hash function:
if hash(obfuscate(password))=SomeValueStoredInTheFile
then pass
In which hash function is something like md5, obfuscate is a function to
scramble the password. Since the value included in the file cannot be
easily reverse calculated to recover the password, the file is secured
(to some degree).

Absolutely.
