When working with large JSON data sets, it's helpful to have a viewer like http://jsonviewer.stack.hu/ which easily parses and renders the object in a tree fashion. [https://github.com/GerHobbelt/nicejson-php/blob/master/nicejson.php PHP code for formatting JSON] to make it "readable" aka "pretty print" is now built-in, as of PHP 5.4, with <code>json_encode JSON_PRETTY_PRINT</code>
There are other tools too for working with json
# Node based https://github.com/ddopson/underscore-cli
# Binary C https://stedolan.github.io/jq/
