For various reasons I have to use Microsoft PowerPoint to prepare presentations, but if I post the slides on-line I want them in HTML format so that they can be viewed without using PowerPoint.

PowerPoint has an “Export to HTML” feature that produces nice-looking slides that can only be viewed with Internet Explorer. Or at least they look terrible in Firefox.

The solution is to load the PowerPoint presentation into OpenOffice.org. OpenOffice has an export to HTML feature that works fine with Firefox and other modern browsers.
