JSON Schema is awesome. It lets you define and validate the schema for your JSON object and is used to define many many JSON structures. For example schemas, please see: schemastore.org/json

However, as great as the format is, without familiarity, it is often very difficult to read JSON Schema and understand exactly what JSON is allowed by the schema. Well, fear not! JSON Schema Viewer to the rescue: just paste a link to your JSON Schema and it will be rendered beautifully, comprehensively and with examples describing the JSON you should expect at evely level of the hierarchy.
