How It Works

This tool analyzes JSON structure and generates TypeScript interfaces with proper type inference:

Nested objects become separate named interfaces
Arrays are typed by analyzing all elements
Null values become unknown | null
Mixed-type arrays use union types

API Endpoint

Content-Type: application/json

{"json": "{\"name\":\"test\"}", "rootName": "MyType"}

Why Use This Tool?

When working with REST APIs or JSON data in TypeScript projects, manually writing interfaces is tedious and error-prone. This converter instantly generates accurate TypeScript types from any JSON payload, saving development time and reducing bugs from type mismatches.
