    Re: |HELP| : How to extract Data from Json file ?
    In the post referenced, the solution only works if the json value is holding a “string”. In my case the database returns some string, numbers, and timestamps. Here is what works with just about any variable type; even json values which contain another json object.

    QByteArray currentByteArray = rep->readAll();
    QJsonDocument json = QJsonDocument::fromJson(currentByteArray);
    QJsonArray jArr = json.array();
    QStringList nameArr;
    QList<int> ageArr;
    QList<double> adubArr;
    QStringList timestampArr;
    for(auto jObj : jArr){
    nameArr << QVariant(jObj.toObject().value(“name”).toVariant()).toString();
                ageArr<< QVariant(jObj.toObject().value(“age”).toVariant()).toInt();
    	    adubArr << QVariant(jObj.toObject().value(“adub”).toVariant()).toDouble();
    
               //in my case the timestamp returns another json object with another set of json values of which one is named date
               timestampArr << jObj.toObject().value("timestamp").toObject().value("date").toString();
    
            }
