CSV to JSON Method with QML

[tacdin]

Hi, I'm selecting a local document with a FileDialog. After selecting the document I want to see the contents of the document. Document format csv. I'm trying to convert from CSV to JSON, but I'm still stuck reading the document content. Even if I read the document content, I cannot view it. Unfortunately, the links I found while doing research are outdated. Can anyone help me on how to read the document and convert it from CSV to JSON?

Attached 1st link offers a solution with C++. I am looking for a JS based solution.
In the second link, TableSerializer, selectionModel, TableModel (displayRoleProvider and editRoleProvider dont work ) give "unknown component" warning.

TableSerializer {
        id: tableSerializer
    }

Component {
        id: tableModelFactory
        TableModel {
            id: tm
            displayRoleProvider: function(row, column, v) {
                var vdata = JSON.parse(v)
                var ret = v
                var val = null
                if (val = vdata["formula"])
                    ret = evaluateFormula(val, row)
                else if (val = vdata["date"])
                    ret = val
                print("displayRoleProvider", row, column, v, ret)
                return ret
            }
            editRoleProvider: function(row, column, v) {
                var vdata = JSON.parse(v)
                var ret = v
                var val = null
                if (val = vdata["formula"])
                    ret = val
                else if (val = vdata["date"])
                    ret = val
                print("editRoleProvider", row, column, v, ret)
                return ret
            }
        }
