I work at Sencha providing crazy fast support on the forums and a lot of times I need to look at the response people are using. Either it’s JSON, JSONP or on a bad day it’s XML. I use JSONLint.com to make the JSON or JSONP readable and also tell me if it’s even valid. JSONLint.com does a fantastic job for me but when I have JSONP I have to manually remove the callback function to only have the JSON or else JSONLint.com will yell at me.
What’s next? First, need to clean it up. Got the first draft done but there is a better way to strip out the callback function. After that I would like to support url calling where you can pass params and headers so you can lint remote JSONP right from JSONPLint.com
