Hey there, since I saw this post before, I though I might also share what I did: I developed a simple webbased graphical interface to view and edit JSON data. Idea is to enrich it with some presets from Minecraft, like the new /tellraw syntax or samples for resource pack files (.mcmeta files). That version is just a in development snapshot, but the basic functionality works, meaning JSON is almost fully supported (except null values). I does not yet support predefined samples, except the one that is the default value. McJSONdon't forget to scroll down I would love to get some feedback.
