How to use Supported JSON Schema Validator

Check types, object properties, required fields, array items, enums/constants and basic numeric/string/array bounds without code generation. Unsupported schema semantics fail explicitly.

  1. Enter input, supported schema json.
  2. Choose the settings for supported json schema validator, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • 100,000 characters per input, depth 40, 10,000 values, 50,000 validation/comparison operations and 1,000 reported errors.
  • Unsupported keywords, including $ref, pattern, format and allOf, are rejected. uniqueItems is limited to arrays of 100 items. JSON numbers retain JavaScript precision.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Can a schema load another URL or execute code?

No. References and unsupported keywords are rejected; validation is a bounded data interpreter.

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.
