Not possible I'm afraid. - incompatible system files with ipad.

You can't.

The iPad runs iOS, a mobile operating system. Microsoft office is only available on Windows and mac OSX.

You can purchase the iPad version of iWork from the app store which contains Pages (word), Keynote (powerpoint) and Numbers (Excell).

I use them and they are very easy and intuitive to use as they have been made especially for the iPad.

They are are also almost 100% compatible with Microsoft Office file formats.
