Use the XLSX file format which can go up to 1 million rows.

Ok,if we r use .xlsx format,then it will handle 1 million rows,but if rows r greater than 1 million,then should be save in 2nd sheet.U can do it through my above code by changing at some point.

              xlApp.UserControl = true;
             Process pro = Process.Start("myfilepath");
