I just want to simply open a document and save it again (i'll worry about editing the cells when i get this bit working)...
Had a frustrating time so far, so i'm sure its something simple:
setincludepath(getincludepath() . PATH_SEPARATOR . '../Classes/');
$objPHPExcel = new PHPExcel();
$objReader = new PHPExcelReaderExcel2007();
$objPHPExcel = $objReader->load("test.xlsx");
// edit cell contents
$objWriter = new PHPExcelWriterExcel2007($objPHPExcel);
My bad, it was an error with the file i was copying.
