      @Christian-Ehrlicher it already gives an error in the last line.

      doc.setArray(root);
      
      : no matching function for call to ‘QJsonDocument::setObject(QJsonArray&)’
          doc.setObject(root);
                            ^

        This is not what you showed us above!

        doc.setArray(root);

          @Christian-Ehrlicher I mixed my code sorry.
          I fixed my problem. Now it seems like: How should i add plan, and route and pt info headings

          [
              {
                  "starting pt": 7,
                  "no": 5,
                  "Total pt": 3
              },
              {
                  "latitude": 3,
                  "longitude": 5,
                  "no": 5,
          
              }
          ]

            I don't understand your question. Already told you that the array is in an object.

              @Christian-Ehrlicher this is what i want to achieve:

              {
                  "Plan" : [
                      { 
                        "route":
                           {
                           "no" : 1.12,
                           "Starting pt" : 1.19,
                           "Total pt" :5
                       },
                        "pt info":
                           {
                            "latitude" : 30.42,
                            "longitude" : 41.19,
                            "no" :5
                
                      }
                     } 
                  ]
              }
              

              And here is mine:

              [
                  {
                      "starting pt": 7,
                      "no": 5,
                      "Total pt": 3
                  },
                  {
                      "latitude": 3,
                      "longitude": 5,
                      "no": 5,
              
                  }
              ]
              

              They are so different from each other. I didnt understand, how can i set a root name like plan, or route and pt info. This is my question

                It's a simply QJsonObject which contains an array

                    This sentence helped me a lot (!)

                    What is so hard to understand?

                    QJsonObject plan;
                    plan.insert("Plan", root);
                    QJsonDocument doc(plan);
                    qDebug() << QString::fromLatin1(doc.toJson());
                    

                    EDIT: it would be better to rename your QJsonArray object root to planArray and plan to root to better match with your json document structure

                    It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)
