How to Use

Basic Conversion

  1. Enter or paste your JSON data
  2. Select the target programming language
  3. Configure generation options
  4. Click "Generate" to create the code

Advanced Options

  1. Customize naming conventions
  2. Set access modifiers
  3. Configure type mappings

Example

Here's an example of converting JSON to TypeScript:

JSON input:

{
  "user": {
    "id": 1,
    "name": "John Doe",
    "email": "john@example.com",
    "preferences": {
      "theme": "dark",
      "notifications": true
    },
    "roles": ["admin", "user"]
  }
}

Generated TypeScript code:

interface Preferences {
  theme: string;
  notifications: boolean;
}

interface User {
  id: number;
  name: string;
  email: string;
  preferences: Preferences;
  roles: string[];
}

interface RootObject {
  user: User;
}

Supported Languages

Primary Languages

  • TypeScript - Interfaces and types
  • Java - Classes with getters/setters
  • Python - Classes with type hints
  • C# - Classes and properties

Additional Languages

  • Kotlin - Data classes
  • Swift - Structs and classes
  • Go - Structs with tags
  • Rust - Structs with derives

Tips & Tricks

  • Clean JSON - Format JSON before conversion
  • Type Names - Use descriptive property names
  • Nested Objects - Create separate interfaces
  • Arrays - Proper type inference for arrays
  • Documentation - Add JSDoc comments

Common Issues

Type Inference

  • Mixed types in arrays
  • Null vs undefined handling
  • Complex nested structures
  • Optional properties

Code Generation

  • Invalid identifiers
  • Reserved keywords
  • Circular references
  • Special characters in names
