    behold, jsonifier▲10

    Just a simple tool I hacked together last night. I wanted to paste a bunch of JSON for reference in an IRC channel, but the JSON that I wanted to paste was not formatted. I didn't quickly find a pastebin that formatted JSON for me so I just made one. It's probably so simple that it's borderline useless, but here it is! http://jsonifier.com/ example output: http://jsonifier.com/paste/4e3f84b46f3b792dde000000
