[beemibrahim]

Also "dump()" returns a C++ string where the entries are in alphabetical order, i want them to be in normal order

That's not dump(), that's the normal behavior of the json type. There is a type for preserving object order.

      nlohmann::json js = nlohmann::json::parse(model_desc);
      std::string pretty_s = js.dump(4);
      std::cout << pretty_s << std::endl;
