Is it possible to have the output from PHPExcel produce a file type that is compatible with Excel used in Windows XP ( .xls file extension?) I haven't been able to find related documentation as of yet.
I see this line that dictates Excel 2007 file output:
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
Is there other options for this?
Thank you for your assistance. Ron
