Ha! I recently launched an analogous service for converting CSVs into Excel files so that web sites can offer users rich spreadsheet downloads instead of crummy CSV files -- goodgrids.com. I posted it to Show HN and just found this! This is great.

Just checked your landing page, great job at making the advantages of your service crystal clear. And of course congrats on launching, always scary to show your baby to the world.
