About this tool
Paste JSON, get TypeScript types and a Zod schema.
Turn any API response into types in one paste. The converter infers nested objects, arrays and optional fields and outputs clean TypeScript types — or a Zod schema for runtime validation. Nothing leaves your browser.
How to use it
- 01Paste a JSON object or array.
- 02Choose TypeScript or Zod output and a root name.
- 03Copy the generated code into your project.
Nested types
Objects become their own named types.
Zod output
Validate API responses at runtime.
Local
Your payloads never leave your machine.
Frequently asked questions
How are arrays of objects handled?
All items are merged; keys missing from some items become optional.
What about null values?
They are typed as null; combine with other samples for a better union.
Is my JSON sent anywhere?
No. Conversion runs entirely in your browser.
