Hi BrowserUk,

I guess you are calling the third field "conditional"? The way I interpreted the input in the OP is a CSV file with four columns: layer name (string), layer number (integer), data types (string), and text type (integer). That the "data types" field was encoded as comma-separated integers in a string is certainly not an optimal design choice and it takes some manual decoding, but unless there's more the OP isn't telling us about the format, I disagree, this looks like CSV to me.

And BTW, I did test before posting (mostly a copy-and-paste from Text::CSV's synopsis):

use Data::Dump 'pp';
use Text::CSV;
my $csv = Text::CSV->new ( { binary => 1 } )
    or die "Cannot use CSV: ".Text::CSV->error_diag ();
open my $fh, "<:encoding(utf8)", "Text_File.csv" or die $!;
while ( my $row = $csv->getline($fh) ) {
    my @vals = split /,/, $row->[2];
    pp $row, @vals;
}
$csv->eof or $csv->error_diag();
close $fh;

__END__

([" NPLUS", 32, 0, ""], 0)
(["NW", 41, 0, 1], 0)
(["NWER", 51, "0,1,2", "12 "], 0, 1, 2)
