JavaScript
var contact = new Object();
contact.firstname = "Jesper";
contact.surname = "Aaberg";
contact.phone = ["555-0100", "555-0120"];
contact.toJSON = function(key)
 {
    var replacement = new Object();
    for (var val in this)
    {
        if (typeof (this[val]) === 'string')
            replacement[val] = this[val].toUpperCase();
        else
            replacement[val] = this[val]
    }
    return replacement;
};
var jsonText = JSON.stringify(contact);
/* The value of jsonText is:
'{"firstname":"JESPER","surname":"AABERG","phone":["555-0100","555-0120"]}'
*/

var jsontext = '{"firstname":"Jesper","surname":"Aaberg","phone":["555-0100","555-0120"]}';
var contact = JSON.parse(jsontext);
document.write(contact.surname + ", " + contact.firstname);
// Output: Aaberg, Jesper
