I've been working on a web based JSON generator called ObjGen that lets users model and generate JSON data interactively using an easy to use shorthand syntax. I wanted to write a tool for quick modeling and prototyping of API values for other projects that I work on. Since putting it online, I've gotten some good user feedback and have heard that it's been helpful for students just learning about JSON and data structures. Check it out here http://www.objgen.com/json?demo=true http://www.objgen.com/json?demo=true I have a couple of other live generators online there too for creating html fragments and java classes, but haven't really updated them in a while. The html generator is Bootstrap aware, but only supports Bootstrap 2 css. The html generator was good for pair mockup sessions, but haven't used it much lately because my other projects are all Bootstrap 3 now.
