Translation Utility with Office Plugin

[obeseotron]

I was looking for a translation program with some type of integration with Word and Excel. Being able to translate a group of cells with single words to another group of cells would really make things a lot easier for me. I use babelfish to do this now, and its really frustrating to have it be web based because i can't do a batch of single words at once. If anyone could help me out with a recommendation I'd appreciate it.

EDIT: Forgot to mention that it has to support German.
