Office 2000 HTML Filter 2.0 is an Office add-on that produces more standard (and lighter) HTML, without all the peculiar non-standard, XMLish tags the original Office output filter uses. It can also export style sheets, or copy formatted text to the clipboard as more humane HTML then the regular copy/paste functionality.
I should get the demons guys to use it.
And I don’t know why it’s classified as an Office add-on on the Microsoft website – it only seems to be available in Word.
