Excel is not included in Windows. Instead it is part of Office, of which
"Office XP" is one version.
You'll have to purchase a version of Office (or a standalone Excel
application - but you can usually get Office, with Word, PowerPoint, and
others thrown in, for less than you'd pay for any two). I'd recommend
Office 2000 or Office 2002. They're cheaper, there's nothing added in
Office 2003 that the vast majority of users need, and the Help system in
Office 2003 is worse than the previous versions.
