Stripping a password from a password protected MS Excel File
Posted by Ben Holness on January 23rd, 2004


Hi,

I have a password protected MS Excel 2002 (or maybe earlier, not sure)
spreadsheet that I would like to be able to open in Startcalc (or
Opencalc, Gnumeric or Kspread - I don't know of any Linux spreadsheet
packages that support passwords). I know the password, I am wondering
whether anyone knows of a utility that will remove the password, given
it is known?

There are some password guessers which claim to be able to remove the
password, but none of them guess my password so they never get to the
stage to remove it It's frustrating, cos I know the password...

Any ideas appreciated.

Cheers,

Ben

The easiest way would be to open/save the file without password
running M$ Excel, doesn't it work with wine? Don't know as we
have openoffice, which works much better then M$ Excel at all.

Can't you change the source code of any of those password guessers
and force it to use the known password?

Gnumeric 1.2.5 can read encrypted files. 1.2.6 will get a back
port of an extension to read the older weaker form of encryption
too. The command line conversion utility 'ssconvert' that is
distributed with gnumeric doesn't handle passwords, so you're
limited to opening and resaving.
