JSON Formatter

This is a light-weight JSON formatter which works on the client side. It is written in JavaScript and uses the JSON.parse() function to parse the JSON string and then uses the JSON.stringify() function to format the JSON object.

If the parse fails then it will attempty to format the object as best as possible with indents and line breaks to make it more readable.
