        $excelrow = 2;

        foreach ($excelresults as $excelresult => $excelvalue) {
            $objPHPExcel->getActiveSheet()->SetCellValue("A" . $excelrow, $excelvalue['event']);
            $objPHPExcel->getActiveSheet()->SetCellValue("B" . $excelrow, $excelvalue['event_title']);
            $objPHPExcel->getActiveSheet()->SetCellValue("C" . $excelrow, $excelvalue['event_date']);
            $objPHPExcel->getActiveSheet()->SetCellValue("D" . $excelrow, $excelvalue['event_start_time']);

            $excelrow++;
        }

        $filename = 'Bowling-Events-For ' . date('Y') . '.xlsx';
        $objPHPExcel->getProperties()->setTitle("Riwaka Bowling Club Events");

        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="' .$filename. '"');
        header('Cache-Control: max-age=0');

        $Writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
        $Writer->save('php://output');
