// If the files uses a delimiter other than a comma (e.g. a tab), then tell the reader
// $reader->setDelimiter("\t");
// If the files uses an encoding other than UTF-8 or ASCII, then tell the reader
// $reader->setInputEncoding('UTF-16LE');

$objWriter = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($objPHPExcel, 'Xlsx');
$objWriter->save('excel_file.xlsx');
