Easy Export

It converts JSON data into Objective-C classes. It identifies types and structure, creating the necessary boilerplate for working with JSON in legacy iOS or macOS applications.

Input your JSON to generate Objective-C classes (header and implementation files). It handles nested objects by creating multiple class pairs.

Objective-C is still used in many legacy projects. This tool simplifies the process of creating data models for these apps, ensuring your Objective-C code matches your JSON data.

Example Input

{
  "id": 1,
  "name": "John Doe",
  "email": "john@example.com",
  "isActive": true,
  "tags": ["admin", "dev"],
  "profile": {
    "bio": "Software Engineer",
    "skills": ["Go", "React", "TypeScript"]
  }
}

Example Output

@interface User : NSObject
@property (nonatomic, assign) NSInteger id;
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSString *email;
@property (nonatomic, assign) BOOL isActive;
@end

Memory Management

Fix: The tool generates properties with appropriate memory management attributes (e.g., `copy` for strings).

Does it support JSONModel?

Yes, you can choose to generate code compatible with the `JSONModel` library.
