JSON toolbox is your all around JSON utility. It can generate code, validate json, tidy, minify and much more!
+ Automatically generate code, so that you don't have to waste time writing it by hand.
+ Validates your JSON on the fly and even shows you exactly where the errors are.
+ Prettify/Tidy your JSON code, making it easier to work with.
+ Minify your JSON code, to use as few bytes as possible.
+ JSON Validation now occurs when a document is loaded. Previously if you loaded a JSON document that already contained errors, it would say success unless manually validated or modified.
+ Added ARC support to generated templates. ARC support works automatically and does not require any user specifications.
