JSON to TypeScript Converter Guide: Types और Interfaces Generate करें (2026)

Converter JSON structure analyze करता है और हर value को TypeScript type में map करता है:

Simple Example

// Input JSON
{ "name": "Raj", "age": 25, "active": true }

// Generated TypeScript
interface Root {
  name: string;
  age: number;
  active: boolean;
}

Nested Object

// Input
{ "user": { "name": "Priya", "address": { "city": "Mumbai" } } }

// Output
interface Address { city: string; }
interface User { name: string; address: Address; }
interface Root { user: User; }

Array of Objects

// Input
{ "users": [{ "id": 1, "name": "Raj" }] }

// Output
interface User { id: number; name: string; }
interface Root { users: User[]; }

1. Sample response fetch करें — Postman, curl, या browser DevTools से
2. Converter में paste करें — Full JSON response
3. Names rename करें — "Root" → "UserResponse", "Item" → "Product"
4. Project में add करें — types/api.ts file में copy करें
5. Manually refine करें — String fields को union literals में tighten करें

// Generated
interface Product { status: string; }

// Refined
interface Product { status: "active" | "draft" | "archived"; }

Thumb rule: API response types के लिए interface। Unions और utility types के लिए type alias।
