Assuming you got your json already loaded:

var json = '{"hola":"ciao"}';

//Parse the JSON: convert it into an object

Your json var will look like:

Object {hola: "ciao", hi: "bye"}

Then you can convert the object to string doing JSON.stringify(parsedJson) and write back to disk/DB if you're manipulating it in your backend (ie.: NodeJs).
