JSON to Zod Schema Generator

Generate a Zod schema from sample JSON when you need runtime validation as well as inferred TypeScript types. Typify maps nested objects and arrays into a validator you can drop into API routes, forms, or config parsing flows.

It is useful for turning uncertain payloads into explicit contracts quickly, especially when you are prototyping or reverse-engineering third-party responses.

Zod schema

"kw">import { z } "kw">from "zod"

"kw">export "kw">const schema = "type">z."kw2">object({
  account: "type">z."kw2">object({
    id: "type">z."kw2">string(),
    email: "type">z."kw2">string(),
    teamSize: "type">z."kw2">number(),
    beta: "type">z."kw2">boolean(),
    features: "type">z."kw2">array("type">z."kw2">string()),
  }),
})

Example

Start with the sample below, then replace it with your own data to generate output instantly.

Input JSON

{
  "account": {
    "id": "acct_123",
    "email": "ops@typify.dev",
    "teamSize": 6,
    "beta": false,
    "features": ["history", "api"]
  }
}

Zod output

import { z } from "zod";

export const rootSchema = z.object({
  account: z.object({
    id: z.string(),
    email: z.string(),
    teamSize: z.number(),
    beta: z.boolean(),
    features: z.array(z.string()),
  }),
});
