Rave Reports Excel File Render Object?

I notice that Rave reports for Delph开发者_运维百科i 7 (default version) comes with PDF, HTML, RTF, and TXT Render Objects. Does anyone know of a place to download a free or opensource render object for Excel, or other file types?

(I am particularly interested in Excel though)

thanks

As a last resort (if someone does not respond with a better solution), i will use the text render object to save the file as a .csv file, which can be opened by Excel
