What is the JSON to TypeScript Interface Tool?
The JSON to TypeScript Interface Tool is designed to help developers quickly and accurately convert any JSON data into fully-typed, readable, and customizable TypeScript definitions. Whether you're working with API responses, configuration files, or mock data, this tool makes generating TypeScript types effortless and error-free.
Understanding JSON to TypeScript Conversion
When working with TypeScript, defining the structure of your data using interface or type helps with:
- Auto-completion
- Compile-time validation
- Clear documentation of expected data shapes
But manually writing TypeScript interfaces from large JSON data can be tedious and error-prone. That's where this tool comes in.
Features and Options
Our generator goes beyond a basic conversion. It offers several customization options to match your coding style or project needs:
🏷️ Kök Arayüz Adı
Define the name of the top-level interface (e.g., User, ProductResponse, AppConfig). This helps ensure clarity and consistency across your codebase.
🔠 Prefix
Add a prefix to all generated types. This is useful for grouping or avoiding name collisions.
Example:
interface ApiUser { ... }
interface ApiAddress { ... }🔄 Oluşturulan Türleri Dışa Aktar
Enable this option to automatically add export at the start of each type/interface—perfect for modular TypeScript codebases.
Example:
export interface User {
...
}💡 Use type Instead of interface
Prefer the flexibility of type aliases? Enable this to generate:
export type User = {
...
}Instead of:
export interface User {
...
