Javascript: How to generate formatted easy-to-read JSON straight from an object? [duplicate]

How can I beautify JSON programmatically?

I know how to generate JSON from an object using JSON.stringify, or in my case the handy jquery-json from google code (https://github.com/krinkle/jquery-json).

Now this works fine, but the output is hard to read for humans. Is there an easy way / function / whatever to output a neatly formatted json file?

This is what I mean:

JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}});  

gives..

"{"a":1,"b":2,"c":{"d":1,"e":[1,2]}}" 

I'd like something like this instead:

{  "a":1,  "b":2,  "c":{     "d":1,     "e":[1,2]  } } 

E.g. with newlines and tabs added. It's much easier to read for larger documents.

I'd like to do this ideally without adding any huge libraries - e.g. not prototype or YUI or whatever.

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces  JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.
