How to serialize to JSON in Qt

Question

How can I JSON serialize a QVariant (or other type of data) in Qt. I don't want to use an external third party library like QJson

Answer 1

Just to mention, as of Qt5, JSON is officially supported:

JSON Support in Qt

QVariant id(1), name("John Doe");
QJsonObject json;

json["Name"] = name.toString();
json.insert("id", id.toInt());
