I alway just use awk to process csv files.

    awk -F '^"|","|"$|,' '{print $2,$3}' whatever.csv

The above works perfectly well, it handles quoted fields, or even just unquoted fields.... This snippet is taken from a presentation I give on AWK and BASH scripting.

That's the thing about AWK, it's already does everything. No need to extended it much at all.
