Preguntas frecuentes

Quick answers.

Which C++ version is required?

The generated code uses `std::optional`, which requires C++17 or later. For older standards, you may need to manually replace these with pointers or third-party optional types.

Do I need any external libraries?

Yes. The generated code is designed to work with the `nlohmann::json` library, also known as JSON for Modern C++, which is a popular header-only library.

How are null values handled?

Fields that are null or missing in the JSON input are automatically wrapped in `std::optional` to reflect their nullable status in the resulting struct.

Can it handle nested objects?

Yes. The tool recursively parses the JSON and creates separate structs for nested objects, ensuring clear organisation and reusability of types.
