- Paste a sample JSON object or array.
- The tool analyzes the structure and generates a JSON Schema (draft-07).
- Copy the schema for use in API validation, documentation, or code generation.
Generate JSON Schema from Data
JSON Schema defines the structure of JSON data for validation, documentation, and code generation. Instead of writing schemas by hand, paste a sample JSON document and get a complete schema automatically.
Schema Features
The generated schema includes type detection, required field inference, format detection (email, date-time, URI, IPv4, UUID), nested object schemas, and array item types. Perfect for API documentation, form validation, and TypeScript/Go type generation.
