JSON Schema is a declarative language for validating the structure and content of JSON documents. It specifies which fields are required, what types they should be, and constraints like minimum/maximum values. This generator analyzes your JSON and produces a Draft-07 compatible schema with correct types, required fields, and nested object definitions — a great starting point for API documentation or form validation.
