Convert JSON to TypeScript interfaces effortlessly.
An open-source tool for developers to generate TypeScript types from JSON objects quickly and securely.

• Fast Conversion: Generate TypeScript interfaces from JSON in seconds.
• Nested Objects Support: Handles deeply nested structures with ease.
• Secure Offline Use: No need to paste your data online—works locally.
• Customizable: Future support for advanced type handling and customizations.

Install the package via NPM:

npm install -g @typeweaver/json2ts

Convert a JSON file to a TypeScript interface:

json2ts convert input.json output.ts

Or use JSON from the clipboard:

json2ts --clipboard

Import and use the package in your Node.js or TypeScript project:

import { convertJsonToTs } from '@typeweaver/json2ts'; const json = { name: "John", age: 30 }; const tsInterface = convertJsonToTs(json); console.log(tsInterface); // Output: // interface Root { // name: string; // age: number; // }

Input JSON:

{ "name": "John", "age": 30, "address": { "city": "New York", "zip": "10001" } }

Generated TypeScript Interface:

interface Root { name: string; age: number; address: { city: string; zip: string; }; }
