JSON to TypeScript & Zod Studio Pro 100% In-Browser
Instant AST type inference, nested interface extraction, and Zod schema generation strictly in local memory
Why Automate JSON to TypeScript & Zod Schema Generation?
When building modern web and fullstack applications with TypeScript, manually declaring dozens of complex types and nested interfaces for REST/GraphQL API payloads is tedious and prone to typos. Furthermore, TypeScript interfaces vanish after compilation, leaving applications vulnerable to unexpected runtime API schema mismatches.
PhuDuy Tools JSON to TypeScript & Zod Studio solves both compile-time typing and runtime validation in a single click: It recursively parses JSON trees into clean PascalCase interfaces while automatically authoring equivalent Zod schemas. Everything executes 100% in client-side browser memory, keeping your proprietary payload schemas strictly confidential.
3 Easy Steps to Generate TypeScript Types
1. Paste JSON or Upload
Paste your API JSON response, upload a .json file, or pick one of the sample presets.
2. Configure Options
Customize root type name, choose between interface vs type, toggle export prefix, and set readonly.
3. Copy or Export
Click Copy to paste definitions directly into your project, or download as a standalone .ts file.

Frequently Asked Questions
When should I use Interface vs Type Alias in TypeScript?
In modern TypeScript, interfaces are recommended for object shapes and class contracts that can be extended, while type aliases are preferred for union types, tuples, or complex mapped types.
What is the benefit of generating Zod schemas alongside TypeScript?
Zod provides runtime validation, verifying external API responses and form submissions before they enter your application logic, complementing TypeScript compile-time safety.
Is my JSON data uploaded to any external server?
No, absolutely not. All parsing and type generation happen 100% locally in your web browser memory.
