If you have tab-delimited data, with unquoted fields, and it is NOT a csv-like format, then
Text::xSV is doing nothing useful for you. Just use split.
my $file = "xxxx.cvs";
open(my $fh, "<", $file) or die "Cannot read '$file': $!";
my $line = <$fh>;
chomp($line);
my @fields = split /\t/, lc($line), -1;
while ($line = <$fh>) {
chomp($line);
my %row;
@row{@fields} = split /\t/, $line, -1;
# save to a db
}
