I have been working with JSON and Hype and I wanted to put another shout out to the Tumult Team.
HyperEdit is a great investment
I know this was an early product from Tumult and Hype is my favorite program by far but this is a very good editor and I find I use it every day.
And at $25 it is a great value.
I also used it to work out all of my PHP for the QRCreator as well.
It is like having all the good tools in my Hype Swiss Army knife!
