PHPExcel saving HTML content to xls/x file

Question

I have this code:

$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'test');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
header('Content-type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename="file.xls"');
$objWriter->save('php://output');

I have 2 problems. Any headers I tried to save the file with .xlsx extension didn't worked. they all gave me a corrupted file.

My second problem which is much more important - this code worked with .xls extension.

But it download a file with all of the HTML content of the page and when I opened it Excell is giving me an error that I missing the css file.

I'm using this code on the page index.php with include(), the css file is called in index.php.

any help would be appreciated, thx!
