Specification
WHAT IS
JSON → MODEL?
JSON Model Generator converts any JSON object into strongly-typed code — TypeScript interfaces or C# classes — in one click. Instead of manually writing types from an API response, paste the JSON and get production-ready type definitions instantly.
When to use it
- →Generating TypeScript interfaces from a REST API response
- →Creating C# model classes from a JSON payload or config file
- →Bootstrapping types when integrating a new third-party API
- →Keeping your types in sync with the actual shape of your data
- →Speeding up backend and frontend development setup
Key Features
- ·Generates TypeScript interfaces with correct primitive types
- ·Generates C# classes with proper type annotations
- ·Handles nested objects and arrays automatically
- ·Infers types from values — string, number, boolean, null
- ·Copy generated code with one click
Privacy & Security Guarantee
WHY IN-BROWSER PROCESSING MATTERS FOR DEVELOPERS
Many online formatters and decoders send your code, JSON payloads, auth tokens, and database schemas to backend servers where they can be cached, logged, or intercepted. ToolBox4Devs guarantees that all processing for JSON → Model runs entirely in your browser's JavaScript V8 engine.
