can't live without it to work with JSON APIs.

the lib from this article is more tailored for apps that want to display arbitrary json to a broad range of users. As someone asked, there are not many uses, but I have one in my web app (http://event-fabric.com/)

Ditto. Between the indentation, colorization, and tree collapsing, I don't need much more from a JSON viewer.

I love it too. Maybe this should be dumped into a Chrome Extension for 'non-technical' people?

Was just about to post this same thing, huge plus one. JSONView is a life saver, highly recommended.

Another vote for JSONView.
