Ask HN: Library to pretty print JSON?

I feel like I am in Google Hell right now. Why is there not a readily available library that I could call to get a clean, pretty printing of my JSON return output within the browser.

The only thing I have stumbled across is: http://www.cerny-online.com/

While it seems to do what I want, it looks for too chunky and complicated just to get some formatted JSON. Call me lazy, but a good old git clone and a function call would be nice.

Is there some buried treasure out there somewhere or do I need to write my own?
