About JSON to JSON Schema
Generate schemas from real JSON
Turn sample payloads into a JSON Schema you can use for validation, docs, and forms.
How it works
- Paste JSON or upload a .json file.
- Choose required and enum detection options.
- Copy or download the schema in your preferred draft.
Key options
- Required fields: flag keys present across objects.
- Enum detection: find repeated values in arrays.
- Type inference: string, number, boolean, and null.
