Programs other than Excel

Well I can't find my Office CD so I can't access MS Excel. Anyone know of alternate programs that can save in .slk format that are Windows compatible?

you can use any text editors .. even notepad .. the .slk format is pretty easy to figure out ..

or you could try star office .. its freeware =)

Thanks! Star Office isn't free anymore, but they had a link to Open Office and I DLed that.
