JSON stringify standalone function for JavaScript

Question

I know of YUI who has a JSON.stringify utility and also of JSON2 from json.org.

What are other good implementations of JSON.stringify?

It should also work in IE6, IE7 and not depend on a framework.

If it depends on anything this should be easily included all in one file.

Edit: I could easily use jquery-json, which was suggested in the comments of the accepted answer. It did what I wanted. (It depends on jquery but that was easily solved)

Answer 1

Well, I would recommend you to stay with the JSON2 library, it is really small (~2.5K minified), and it uses native implementations if available.

This small standalone library is also compatible with the JSON object described in the ECMAScript 5 Edition Standard.

Answer 2

Consider "json-sans-eval". I'm using this in Myna now because it is super fast, ECMAScript 5 conformant, and most importantly, unlike JSON2, it does not use eval() so there is no danger of someone abusing the JSON spec to execute trojan JavaScript code.
