Convert TypeScript Types to Zod Schemas

Zod provides runtime validation for JavaScript and TypeScript applications. When your data models are already defined as TypeScript interfaces or type aliases, writing matching Zod schemas by hand is tedious. This tool generates Zod schema code from your TypeScript definitions with real-time output.

Features

Paste exported interfaces and type aliases to receive ready-to-use Zod schema constants. Optionally keep TSDoc comments in the output or skip JSDoc-based validator annotations. Every exported type becomes a schema following the TypeNameSchema naming convention.

To generate Zod from JSON samples instead, use JSON to Zod. For JSON Schema as the intermediate format, try JSON Schema to Zod. To generate TypeScript from JSON Schema, use JSON Schema to TypeScript.

Frequently Asked Questions

Which Zod version does the output target?

The generator produces Zod v4 compatible schema code, including updated string validation methods and improved function type handling.

What does "Skip Zod validators from JSDoc annotations" do?

When disabled, TSDoc tags such as @min, @max, and @format are parsed into Zod validators. Enable this option to generate plain structural schemas without JSDoc-derived constraints.

Do I need to export my types?

Yes. Only exported interfaces and type aliases are converted into Zod schemas. Non-exported types used internally may still appear as nested schema references.

Is my TypeScript code sent to a server?

No. Schema generation runs entirely in your browser using the ts-to-zod library. Your source code stays on your device.
