Data conversion

[Travis Roy]

Hi, I'm looking for two things, they might both be in the same package,
but I can't find either, at least from a command line.

I'm looking to convert something from Excel to CSV and then from CSV to
fixed with or "Standard Data Format" as dBase calls it.. Example:

FirstN     LastN      EMail
Travis     Roy        travis at scootz.net
Joe        Bob        joe at bob.com


Has anybody heard of anything like this for the console for Linux? I've
been searching and can't find anything.
