Upgrading to Microsoft Office XP from a previous version of Office is a straightforward process. The file formats for Microsoft Word, Microsoft Excel, and Microsoft PowerPoint have not changed since Office 97, and users upgrading from these versions do not need to convert any files. Microsoft Outlook 2002 users can continue to use data files and address books created in Outlook 2000. Microsoft Access 2002 users can work with databases in two file formats — Access 2000 and an enhanced Access 2002 format.
