How to use Supported Schema Example Generator
Create a small structural example from declared types, required properties and supported bounds. The result is validated against the same named subset before it is returned.
- Enter input.
- Choose the settings for supported schema example generator, then run the tool.
- Review the result and any limitations before copying or downloading it.
Good to know
- Uses the Supported JSON Schema Validator keyword subset only; unknown keywords,refs,patterns,composition and formats are rejected.
- 20 generation levels,1000 generation values,100 array items,1000 string code points. Some satisfiable schemas have no deterministic example under this strategy and are refused; no meaningful real-world data is invented.
- Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
Common questions
Does a failure prove the schema is unsatisfiable?
No. It means this bounded deterministic strategy could not produce and verify an example.
Is this input sent to a server?
No. The application processes this input inside your browser tab and does not save it to persistent storage.
