I see a few tutorials pertaining to exporting data into an Excel spreadsheet. Looks straightforward, however I do not own Excel. I use Open Office (hey, it's free). I'm able to open Excel spreadsheet within Open Office Calc. However when I write my code, and I goto reference Excel, it's not there. Well I can figure this due to the fact I dont own Excel. Now Open Office doesnt show either.

So I was wondering if there is a way I can create an Excel file, without having Excel installed? Maybe download a component that allows me to, or maybe another work around?
