If it is coming from Excel, the rules are something like this
(borrowed from the Text::CSV documentation):

  * A field MAY be surrounded by double quotes.
  * A field that contains a comma MUST be surrounded by double quotes.
  * A field containing double quotes MUST be surrounded by double
    quotes, and the embedded double quotes MUST be represented by a
    pair of consecutive double quotes.

It's ridiculously complicated.

That sounds like a challenge.  ;-)

Seriously, I had to take a look at the Text::CSV man page.  All you'd
need to change in the script you posted is do something like this:

    use Text::CSV;
    my $csv=Text::CSV->new;

    while (<INPUT>) {
        chomp;
        $csv->parse($_) or die "Invalid input at line $.: $!\n";
        @fields = $csv->fields();

instead of

    while (<INPUT>) {
        chomp;
        @fields = split /,/;

or whatever.

Basically, you're looking at an extra 3 lines to ensure correctness.
(And, honestly, having dealt with CSV from Excel before, your script
would probably have broken pretty badly.)

BTW, personally I'd just add the extra step to insert the DBI calls.
If you understand SQL, DBI is ridiculously simple.
