Hi Perlmonks,

I am trying to get the transpose of a .csv file. When I executed the code below, I get the error message "Can't use a string (" ") as an ARRAY ref while "strict refs" in use at line 17". I am not sure how to solve this problem. 

#!/usr/bin/perl -w
use strict;
use warnings;
use Text::CSV_XS;

open(my $FILE1, '<', "inputfile.csv") or die "cannot open file1 $!\n";
open(my $FILE2, '>', "outputfile.csv") or die "cannot open file2 $!\n"
+;
my $csv =Text::CSV_XS-> new({binary=> 1, eol=> $/, sep_char=> "\t", al
+ways_quote=>1});

my @tfields;

while(my $row=$csv->getline($FILE1))
{
    my @fields=@$row;
for my $y (0..(@fields-1)) {
    
    for my $x (0..@{$fields[$y]}-1) {
     $tfields[$x][$y] = $fields[$y][$x];
      $csv->print($FILE2,\@tfields);
    }
}

}
