The Tableizer

This free and fast little tool converts spreadsheet cells into HTML so they can be published on the web or embedded directly into a webpage as an HTML table. You copy-and-paste the Excel or Calc spreadsheet cells into the box, choose the font size, font style and header color, click the Tableize It! button, and it spits out the code and a preview of what the table will look like.
