Thanks, great stuff.
I have commas inside string fields like this:

a,b,c
4207416,"[0,9,3,3,0,0,0,0,0,0]",56.0

So threw in an awk to replace separators outside strings to semicolons ( using @John1024's answer ):

function pretty_csv {
    perl -pe 's/((?<=,)|(?<=^)),/ ,/g;' "$@" \
        | awk -F\" '{for (i=1; i<=NF; i+=2) gsub(/,/,";",$i)} 1' OFS='"' \
        | column -t -s';' \
        | less  -F -S -X -K
}

which results in:

a        b                        c
4207416  "[0,9,3,3,0,0,0,0,0,0]"  56.0
