Answer 1

I think there is a simpler one:

use JSON ();

$content = "{WHATEVER JSON CONTENT}";

$content = JSON->new->utf8->decode($content);

Answer 2

Here is a snippet to convert the JSON. Modified to catch errors.

use strict;
use warnings;
use JSON::XS;
use Try::Tiny;
use Data::Dumper::Concise;

my $data = qq<[{"success":"21","data":[{"name":"tester","lastname":"project"}]}]>;

my $decoded;

try {
    $decoded = JSON::XS::decode_json($data);
}
catch {
    warn "Caught JSON::XS decode error: $_";
};

print Dumper $decoded;
