JSON Schema Tools

Question

I am writing a specification and should describe some JSON objects. Large JSONs tend to get too confused with text and tabs alone. Is there a (preferably) online tool for creating charts, such as http://www.json.org/ or http://www.sqlite.org/lang_altertable.html . They use them to describe syntax, but is there anything similar for describing JSON objects? They perfectly represent the objects that are required, optional, arrays, etc.

Answer 1

These types of syntax diagrams are known as railroad diagrams.

There is an interactive tool http://bottlecaps.de/rr/ui that you can use to create your own charts. You must indicate your grammar in EBNF notation.
