I need to export MySQL dataTable using wpf to an Excel sheet, which can be done.
My exported data will then be pasted beginning in cell "A1" of the Excel sheet.

Is there a possibility to put it into a specific cell? I need to export the data frame to a range beginning at cell A5. Is this possible?

What I have tried:

here is my exporting code it works perfectly :

private void export_Click(object sender, RoutedEventArgs e)
        {
            using (var conx = new MySqlConnection(constring))
            {
                conn.Open();

            //// extraction excel 

            string Mysql = null;
            string data = null;
            int i = 0;
            int j = 0;

            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;

            object misValue = System.Reflection.Missing.Value;

            xlApp = new Excel.Application();
            xlApp.Visible = true;
            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);


            Mysql = "SELECT * from database.Table";

            MySqlDataAdapter cmd = new MySqlDataAdapter(Mysql,conn);
            DataSet ds = new DataSet();
            cmd.Fill(ds);

            for (i = 0; i <= ds.Tables[0].Rows.Count-1 ; i++)
            {
                for (j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
                {
                    data = ds.Tables[0].Rows[i].ItemArray[j].ToString();
                    
                    xlWorkSheet.Cells[ i+1, j+1] = data;


                }

            }
           }

           }
