Thank you so much!! That's so useful!! But now I have a new problem. I'm completely begginer and I can't understand it. The problem is that I have to read the json file from my script. I've try like this: 
use strict;
use warnings;
 
binmode STDOUT, ":utf8";
use utf8;
 
use JSON;

my $json;
{
  local $/;
  open my $fh, "<", "struc_cover_edu.json";
  $json = <$fh>;
  close $fh;
}

my $j = JSON->new->decode($json);
for my $s (@$j) {
        next unless $s->{PROT_NAME} eq 'XPA';
        for my $p (@{$s->{COVERTURA}}) {
                print $p->{PSTART},"\n";
        }
}

But an ERROR appears: Not an ARRAY reference at script.pl line 20. (line 20 is that one: for my $s (@$j) ) how could I solve it? thanks thanks thanks!!!
