Pretty-printing JSON and XML on Mac OSX

JSONView Chrome Extension: https://chrome.google.com/webstore/detail/chklaanhfefbnpoihc...

XML Tree Chrome Extension: https://chrome.google.com/webstore/detail/gbammbheopgpmaagmc...

And JSONlint.com to copy/paste JSON from wherever: http://jsonlint.com/

Also love that Chrome dev tools now pretty prints JSON returned from XHRs in the network response tab.
