You should have a copy of sheets to go available to you with 4.5 OS. You will need to register your copy of Docs To Go to activate it. Look for Word to Go in your application folder - or on your desktop, open it, press the menu key and select register. This will put a copy of the excel app on your device. Once registered, press the menu key again and select check for updates. There will be a newer free version to download.
