Answer 2

I copied the text from your question, everything turned out fine

$objPHPExcel = new PHPExcel();
        $objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'Hello')
            ->setCellValue('B2', 'world!')
            ->setCellValue('D2', 'Betrag €');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
        $objWriter->save(str_replace('.php', '.xls', __FILE__));
