    @Vineela First, you need to make sure you parsed Json correctly. The code I posted does not do that!
    Then please show your current code (reading Json and putting entries into combo box).
    One more question: are you sure you actually got the reply from server with Json?

    @jsulm

    void MainWindow::datainDaHouse2(QByteArray data)
    {
    //first
     qDebug()<< "Jason value" +data;
     QJsonDocument doc = QJsonDocument::fromJson(data);
        QJsonArray array = doc.array();
        QJsonObject object = array.at(0).toObject();
        QString code = object["LeaderCode"].toString();
    
            ui->comboBox_54->insertItem(3,code);
         //second
            qDebug()<< "InsertCode" +code;
    }
    

    well this is my current code and my output for qDebug is,
    //first
    "Jason value<pre>[\n {\n "LeaderCode": "GNL0001"\n },\n {\n "LeaderCode": "GNL0002"\n }\n]</pre>"
    //second here where my output getting blank
    "InsertCode"

      @Vineela Your Json string is invalid as it contains <pre></pre>. You need to remove these HTML tags first.

      data = data.replace("<pre>", "").replace("</pre>", "");
      QJsonDocument doc = QJsonDocument::fromJson(data);
      QJsonArray array = doc.array();
      QJsonObject object = array.at(0).toObject();
      QString code = object["LeaderCode"].toString();
      
      ui->comboBox_54->insertItem(3,code);
      //second
      qDebug()<< "InsertCode" +code;

          @Vineela Come on! If you get GNL0001 via array.at(0) then you get GNL0002 via array.at(1)...

                @jsulm well I've added this
                for(int i=0 ;i<array.size();i++){
                QJsonObject object = array.at(i).toObject();
                } it worked

                    Yes, if you do this in a loop then you need to use index (i in your case) instead of fix numbers.

                                @Vineela Not sure what you mean?
                                You mean if you get new data and add new entries to your combo box you then have same values several times?
                                In this case you need to filter new values and only add values which are not yet in the box.
