About JSON to Zod Schema
JSON to Zod Schema generates Zod validation schemas from a JSON sample. Paste any JSON object or array and get TypeScript Zod schema code that validates the same structure — with z.string(), z.number(), z.boolean(), z.object(), z.array() and other Zod types inferred from the sample data.
Zod is the most popular TypeScript validation library, widely used with tRPC, Next.js API routes, and form validation. Building schemas by hand from large API response objects is time-consuming. This generator creates a solid starting point in seconds.
The output is ready to use in your TypeScript project with the Zod library.
