The standard JavaScript way to do this would be to use JSON.parse: var myArray JSON.

When making a request, set the dataType attribute to ‘json’ to have jQuery automatically parse the returned JSON string. If you're retrieving the JSON files separately via AJAX, then you only need to make sure that the JSON files are served with the correct Content-Type and charset: Content-Type: application/json charset'utf-8'). With jQuery, you can use the $.ajax() method, which automatically detects and parses JSON data for you. ajax success method var someVar JSON.parse(data) console.log(someVar) You can also set it to a global variable temporarily to debug it via the Firebug/Chrome DevTools console by typing its name. One common use case for JSON data is when you are fetching data from a server using AJAX. Use console.log or console.dir in combination with JSON.parse to show the actual object that is returned from the JSON.parse.
