Why convert JSON to TypeScript?

Converting **JSON to TypeScript** allows developers to ensure **Type Safety** in their applications. By generating an `interface` that matches the structure of your API's JSON response, you catch errors at compile-time (like accessing a missing property) rather than runtime, significantly improving code reliability and developer experience (IntelliSense).

How to Generate TS Interfaces

  1. 1

    Paste JSON

    Paste your JSON data into the left editor. It can be a single object or an array of objects.

  2. 2

    Set Root Interface Name

    Define the name for your main interface (e.g., `IUser` or `Product`). The tool handles naming for nested objects automatically.

  3. 3

    Use in Application

    Copy the generated code and paste it into your `types.ts` file. You can now use this interface to type your API calls and props.

Features

Strict Typing

We don't just use `any`. We infer precise types (`number`, `boolean`, `string`) to give you full type safety benefits.

Nested Interfaces

If your JSON has nested objects, we extract them into their own named interfaces to keep your code clean and reusable.
