Convert JSON to a Zod schema

Paste a JSON sample and get a Zod schema you can drop straight into your TypeScript project. Objects become z.object, arrays become z.array, and primitives map to z.string, z.number, and z.boolean — a runtime-validation schema that mirrors your data's shape.

It runs entirely in your browser with no upload and no account, so you can turn an API response into a validated schema in seconds.

JSON to Zod Schema Converter — frequently asked questions

How do I generate a Zod schema from JSON?
Paste your JSON on the left and the Zod schema appears on the right, ready to import alongside zod. Set the schema's variable name and copy it into your project.
What Zod types does it produce?
Objects map to z.object, arrays to z.array, and primitives to z.string, z.number, and z.boolean, with nesting preserved. Pair it with z.infer to derive a matching TypeScript type from the schema.
Is my JSON uploaded anywhere?
No. Parsing and code generation run entirely in your browser with JavaScript — your JSON never leaves your device, so it's safe to paste API responses and other sensitive payloads. It's free with no sign-up; a single unobtrusive ad slot covers hosting.
