Instantaneously generate a valid JSON Schema (Draft‑07) from any sample JSON object. Simply upload or paste your JSON, and the tool infers data types, required fields, nested object structures, and array item types. Download the schema as a `.json` file or copy it to your clipboard – perfect for API documentation, validation rules, or server‑side models.
The inferred schema is based on the types and structure of the provided sample. It sets all observed properties as required by default and does not add arbitrary constraints (like enum or minLength).
The tool still generates a valid schema with the correct root type – for example 'array' with inferred items, 'string', or 'number'.
Yes, a settings panel lets you allow additional properties and make all fields optional, giving you control over the generated schema.
