JSON to Types Generator
Convert JSON to TypeScript, Zod, Go, and Python types instantly. Fast, private, and error-detecting.
About the JSON to Types Generator
The JSON to Types Generator by Grab-Kit is a free online tool designed for full-stack developers and software engineers. Writing type definitions manually is tedious and error-prone, especially when dealing with large API responses. Our tool automates this process by analyzing your JSON payload and instantly generating strongly-typed structures for multiple programming languages, saving you hours of boilerplate code.
Using the generator is incredibly simple. Paste your JSON data into the left input box. The tool instantly validates the JSON and detects syntax errors. If the JSON is valid, it recursively parses the structure and generates the corresponding types. You can switch between TypeScript interfaces, Zod validation schemas, Go structs, and Python TypedDicts using the tabs on the right. Click the "Copy" button to instantly copy the generated code to your clipboard and paste it directly into your IDE.
Why use Grab-Kit?
All our tools, including the JSON to Types Generator, run entirely in your browser. This means your API payloads and data structures are never uploaded to or stored on any server, ensuring 100% privacy for your backend architecture. It is completely free, requires no signup, and works flawlessly on both desktop and mobile devices.
