JSON.parse is your friend and answer :)

//examples:
JSON.parse('{}'); // {}
JSON.parse('true'); // true
JSON.parse('"foo"'); // "foo"
JSON.parse('[1, 5, "false"]'); // [1, 5, "false"]
JSON.parse('null'); // null

MDN JSON.Parse details

Beware of browser compatibility issues, as noted on this link: developer.mozilla.org/en-US/docs/JavaScript/Reference/…. – rcdmk May 19 '13 at 18:34

it's supported in IE8..caniuse.com/json – Dory Zidon May 19 '13 at 18:49
    
Well... It all dependes on the target audience, but I think it's always better to use a polyfill like json2 in case the browser does not support the native APIs. – rcdmk May 19 '13 at 18:58
