I've used the Ruby spreadsheet gem with success. It's a bit old, but works ok.

Ah, a port of Perl's module... good to know.

Makes you wonder how soon it'll be before languages that are out of favor but have great libraries written for them are mainly viewed as targets for mining ideas and techniques, like how the various open source kernel developers use each other's kernels as driver documentation.

I've used this extensively for generating spreadsheets, and it's pretty awesome.
