How to use this tool
Turn a representative JSON response into a starting point for typed models. It is useful when documenting an API or bootstrapping client-side types.
Suggested workflow
- Paste a realistic sample response.
- Select the destination language and naming options.
- Review optional fields and generated types before adding them to production.
Good to know
Use several real samples when an API has optional fields; one sample cannot describe every response shape.
