JSON Schema Validator
Validate JSON data against a JSON Schema (Draft 7) — type, required, enum, min/max, and more.
✓ Valid — JSON matches the schema.
How JSON Schema validation works
JSON Schema (Draft 7) is a vocabulary for describing the structure of JSON data. This tool validates the keywords most commonly used: type, required, properties, additionalProperties, enum, minimum/maximum, minLength/maxLength, pattern, items, minItems/maxItems, and nested objects recursively.
To generate a JSON Schema from existing data, use JSON Schema Generator. For TypeScript types, try JSON to TypeScript.
Private & free — this tool runs entirely in your browser.
