If you are looking for a free program that offers a replacement for MSWord, Excel and even PowerPoint then you should consider Open Office.
Open Office is an open source suite that resembles Microsoft Office 2003. The features are all very similar and the functions are what you may remember before MS Office 2007 arrived with its controversial ribbon interface. Open Office is capable of viewing, creating, exporting and importing any of the files that are used within Microsoft Office (that includes the 2007 version as well).
