I'm pretty sure I got it free as an "App of the Day" early on.
There are other apps that also work. . . .let me find links.
This one's called "Quick Office". This is the paid version, $10ish, but there's a free version as well.
This one's more for the full version, $15ish; again, also a free version. It's called "Office Suite Pro".
