LaRue,
To read MS Excel, or Word documents on either an iPad or and Android device you need an App called "Documents To Go". (there are others but this one is rated the best) The Read-Only version is free (for my Android) which allows you to read Excel and Word documents, but not update them. The full version of Documents To Go allows you to edit Excel and Word documents and cost about $15.00 for the Android. I suspect that the iPad version would be similarly priced.
