@nlohmann could you please expand on your answer. I did check out the arbitary type conversion but it is not giving me enough information. I am adding from_json function to my class to parse it based on the link you suggested. How do we parse json into a std::vector... the get_to doesn't accept std::vector. Please feel free to use the author's classes for explanation

[nlohmann]

You can only parse into a JSON value (the parse function returns json, and the conversions go from/to json). In the example, after parsing the JSON`, you could have code like:

std::ifstream myinput("myfile.json");
auto j = json::parse(myinput);

std::vector<myclass> v = j["Configuration"];
