Just use to_json() to go from perl to json, and from_json() to go from json to perl. Here's an example:

use strict;
use JSON;
use Data::Dumper;

# Here's some data
my $data = {
  A => 1,
  B => "hello world",
  D => [
    [
    'dog',
    'cat',
    'bird',
    ],
    [ 'red','green','blue'],
  ],
  D => {
    X => 1,
    Y => 2,
  }
};

# print the data
print Dumper($data), "\n";

# convert perl data to json, then print out the json
my $json = to_json($data);
print "$json\n";

# convert the json back to perl, then print it.
# should be the same as before
my $data2 = from_json($json);
print Dumper($data2), "\n";
