      QFile f(QString("%1.csv").arg(QDateTime::currentDateTime().toString("ddMMyyyy-hhmmss"));
      
      if (file.open(QIODevice::WriteOnly | QIODevice::Text))
      {
         // write your csv data here
      }

        @ambershark Thanks
        it work for me
        QDateTime now = QDateTime::currentDateTime();
        QString timestamp = now.toString(QLatin1String("yyyyMMdd-hhmm"));
        QString filename = QString::fromLatin1("/path/%1.csv").arg(timestamp);
        QFile file(filename);
        if(!file.open(QIODevice::WriteOnly | QIODevice::Text))
        {
        // write data
        }
        file.close();
