JSON to Zod schema generator
Infer a clean Zod validation schema and TypeScript type from sample JSON locally in your browser.
How to Use JSON to Zod schema generator
- Paste sample JSON data and customize your schema identifier.
- Review the result and its visible context before using it.
- Copy, download, or save only the output you need.
Purpose & Processing Boundary
Infer clean, idiomatic Zod runtime validation schemas and TypeScript types directly from sample JSON payloads with zero server uploads.
Inferred schemas handle standard string formats (datetime, email, url, uuid), numbers, booleans, arrays, and objects. Refine custom refinements and constraints as needed for business logic.
Frequently Asked Questions
What is Zod and why convert JSON to Zod schemas?
Zod is a TypeScript-first schema validation library. Converting JSON into Zod schemas allows you to validate runtime API responses, user inputs, and environment variables while automatically deriving static TypeScript types.
Does the generator recognize dates, emails, and URLs?
Yes. The inferrer detects ISO 8601 datetimes, email addresses, HTTP/HTTPS URLs, and UUIDs to produce specialized Zod string validators such as z.string().datetime() and z.string().email().
Is my JSON payload uploaded to an external server?
No. The schema inference runs 100% in your local browser runtime. No data is stored, sent over the network, or logged.
