Такой код:

ORDER BY dt_added DESC';
//echo $sql."<br />";
$result=mysql_query($sql, $con);
if(!$result){ echo mysql_error(); }

include('PHPExcel.php');
$objPHPExcel = new PHPExcel();

$objPHPExcel->getDefaultStyle()->getFont()->setName('Arial')
                                          ->setSize(10);
