The Office HTML Filter is a tool you can use to remove Office-specific markup tags embedded in Office 2000 documents saved as Hypertext Markup Language (HTML). When you create an HTML document in Office 2000, Office-specific markup tags are embedded in it. These tags help "round-trip" the document for editing purposes. For example, if you create the document in Word 2000 and save it as HTML, the code embedded in the document allows you to re-open the document in Word 2000 and use the same features you originally used to create the page.Once you have completed editing an HTML document in Word 2000 or Excel 2000, you can use the Office HTML Filter to remove the Office-specific markup tags from the final copy of the HTML document. By removing the tags, you reduce the size of the document, which in turn reduces both the amount of space used on Web servers as well as the time it takes to download the page.
