The JSON Schema Generator analyzes a sample of your data and produces a JSON Schema (Draft-07) that describes it: property types, required fields, array item shapes, formats (like email or date), and constraints. Use it to document a contract, validate future payloads, or bootstrap an API spec. You can apply the generated schema straight to the validation panel in one click.
