JSON to TypeScript

Automatically generate TypeScript interfaces from DevTools network requests.

🚀 JSON to TypeScript – Interface Generator from API Stop writing TypeScript interfaces by hand or using AI chats. This extension helps you instantly generate TypeScript interfaces from real API responses — directly inside Chrome DevTools. No more copying JSON. No more switching between tools. No more repetitive typing. 💡 What problem does it solve? If you're a frontend developer, you know the pain: * You open the Network tab * Find an API request * Copy JSON response * Paste it into some online converter or AI chat * Fix types manually * Repeat… again and again It’s slow, annoying, and error-prone. JSON to TypeScript solves this in one click. ⚡ How it works 1. Open Chrome DevTools 2. Go to the "JSON to TypeScript" tab 3. Enable recording 4. Make an API call 5. Click any API request 6. Get a ready-to-use TypeScript interface instantly Everything happens locally in your browser. 🔥 Key Features 🧠 Generate interfaces from real API responses No fake data. No manual input. Works directly with actual backend responses from the Network tab. ⚡ Live workflow inside DevTools No need to leave your development environment. Everything is integrated into Chrome DevTools. 🧩 Smart type detection Automatically detects: * primitives (string, number, boolean) * nested objects * arrays * nullable fields * mixed types (union types) 🏷 Custom interface naming Configure how your interfaces are named: * Prefix (e.g. IUser) * Suffix (e.g. UserDTO) * Full control over naming conventions ✏️ Editable output Generated interface is fully editable: * tweak types * rename fields * adjust structure 📋 One-click copy Copy generated code instantly and paste into your project. ⭐ Favorites Save important DTOs for later use. No need to regenerate the same structures again. 🌙 Light & Dark mode Choose your preferred theme. 🌍 Localization Supports: * English * Russian 🔒 Privacy-first * No data is sent anywhere * No tracking * Works 100% locally 🎯 Who is this for? * Frontend developers (React, Vue, Angular, etc.) * TypeScript users * Developers working with REST APIs * Anyone tired of writing DTOs manually 🆚 How is it different from other tools? Most tools: * require manual JSON input * work as standalone converters * break your workflow This extension: * works directly with API responses * lives inside DevTools * fits naturally into your development process 💬 Example Instead of this JSON: { "user": { "id": 1, "name": "John" } } You instantly get: export default interface IUserDTO { user: IUser; } interface IUser { id: number; name: string; } 🏁 Summary ✔ No more manual DTO writing ✔ No more copy-paste workflows ✔ Faster development ✔ Cleaner TypeScript code Build faster. Focus on logic — not on typing interfaces.
