Dick,

I'm pretty sure you'll need a converter for that. By doing a Google search for "free xls to html converter" you should get quite a few hits. Some offer free trial and if you dig far enough you might even find a free download. Or it's my understanding that if you sign up for a Google Gmail account (free), they have a converter bundled within that mail platform for free usage. Here's a link: http://mail.google.com/mail/help/intl/en/about.html

Best of luck,

Sam
