in thread Adding rows of data

Well, then at least add a hash reference instead of two array references to match data structure from your _test() ... 

...
push @{ $header_row }
  , [ { 'City Name' => ''
      , ...
      }
    ] ;
...

BTW|FWIW, your headers|key names are different in letter case & spellings.

    That should work for that kind of data structure, my final data structure goal is to have it as this once printed:
    my $data_test = [
          [
            'City Name',
            'Last Name',
            'First Name',
            'Address',
          ],
          [
            '',
            '',
            '',
            '',
          ],
          [
            'San Frans',
            'Doe',
            'Jonh',
            '100 Main Street',
          ],
];
