Infer practical TypeScript, Zod, and Pydantic model scaffolds from JSON sample data. Arrays of objects are merged so optional fields remain visible.
Paste an API response, fixture, or configuration object. The sample stays in this browser.
Generate from a JSON sample to create TypeScript types.
Inference is based on the supplied sample. Review IDs, nullable values, date strings, and business constraints before using generated types in production.
Use the TypeScript output as a fast model scaffold, the Zod schema for runtime validation, or the Pydantic models for Python API code. No JSON is sent to KivTools or another service.
