Automate TypeScript Typing

Writing TypeScript interfaces for large API responses is tedious and error-prone. This tool automates the process by parsing your JSON and generating the corresponding interface definitions instantly.

Features

  • Nested Objects: Automatically creates separate interfaces for nested JSON objects.
  • Arrays: Detects array types, including arrays of objects.
  • Smart Naming: Uses property names to generate readable interface names (e.g., users becomes UsersItem).

Who is this for?

Perfect for React, Angular, Vue, and Node.js developers using TypeScript. Simply paste a sample response from Postman or your browser's network tab, and get type-safe definitions in seconds.
