Convert API JSON to TypeScript Interfaces in 1 Click ⚡

If you’ve ever worked with APIs in TypeScript, you know the pain:

You receive a JSON response, and then you manually write out the interface for it. It’s boring, repetitive, and error-prone.

What if you could generate a TypeScript interface instantly from any JSON?

That’s exactly what JSONToAll Tools does 🚀.

🤔 The Problem

APIs often return complex JSON objects:

{
  "id": 1,
  "name": "Sourav",
  "address": {
    "city": "Kolkata",
    "pincode": 700001
  },
  "isActive": true
}

Manually creating a matching TypeScript interface takes time:

export interface Root {
  id: number;
  name: string;
  address: {
    city: string;
    pincode: number;
  };
  isActive: boolean;
}

⚡ The Fast Solution

With JSONToAll Tools, you simply paste your JSON → click convert → and get a fully typed interface instantly.

• ✅ Works with nested objects
• ✅ Automatically infers correct types
• ✅ Handles arrays
• ✅ Free to use

🎯 Example

Input JSON:

{
  "id": 101,
  "title": "Blog Draft",
  "tags": ["typescript", "json", "devtools"],
  "published": true
}

Generated Interface:

export interface Root {
  id: number;
  title: string;
  tags: string[];
  published: boolean;
}

🔥 Why It Matters

• Saves hours of manual typing
• Avoids silly mistakes in typing
• Improves productivity for frontend & backend devs
