Start by pasting your C++ class, struct, or object initialization that needs to be converted to JSON format. The tool supports modern C++ features, STL containers like std::vector and std::string, and nested structures.

class Person {
public:
    std::string name;
    int age;
    std::string email;
    bool isActive;
    std::vector<std::string> roles;
};

Person person;
person.name = "John Doe";
person.age = 30;
person.email = "[email protected]";
person.isActive = true;
person.roles = {
    "admin", "developer"
};

Click the green "Convert" button to send your C++ code to our AI-powered backend API for processing. The converter intelligently transforms modern C++ syntax to JSON format, handling STL containers, booleans, vectors, and proper quote formatting.

{
  "name": "John Doe",
  "age": 30,
  "email": "[email protected]",
  "isActive": true,
  "roles": [
    "admin",
    "developer"
  ]
}

The tool produces properly formatted, valid JSON that's ready to use in your web applications, REST APIs, game development, or configuration files.

Copy the JSON to your clipboard or download it as a .json file for use in your C++ projects, game development, or cross-platform applications.
