BlackBerry Curve 8330

I am looking for a program which would allow me to view my excel and word documents on my memory card. I have searched for one over the last week to no avail. I am not willing to pay $50-$60 to do this. Does anyone know where I can download a free program which would allow me to do this? I don't need to edit the docs, even though it would be nice. I have the Sprint 8330 and love it. I just want to view documents like I did on my Treo 755p. Thanks for the help.
