Download open office. It's compatible with all office formats, and it's free.

Run the uninstaller which is located in:

/Applications/Microsoft Office 2008/Outils supplémentaires/Supprimer Office

Which translates as

/Applications/Microsoft Office 2008/Extra tools?/Uninstall Office

Or something like that.
