For those that prefer a command line tool, jq has been around for a while and works very well.
I can't count how many times jq let me hack together a bunch of commands I normally would have had to write a small program for. e.g small script that pushes the latest semver tag from a github repo to a geckoboard text widget: <a href="https://gist.github.com/jdc0589/67df901f71d96b7649b4" rel="nofollow">https://gist.github.com/jdc0589/67df901f71d96b7649b4</a><p><a href="http://stedolan.github.io/jq/" rel="nofollow">http://stedolan.github.io/jq/</a>
The video looks like you are combining keys?<p>You could just do this with <a href="http://jsonunroller.appspot.com/" rel="nofollow">http://jsonunroller.appspot.com/</a> and grep.
