Is it possible with phpexcel library to read xml formated excel file and  convert it into BIFF formated file.

Perfectly possible, as long as the xlsx doesn't contain any features that aren't supported by xls (BIFF)


/** PHPExcel_IOFactory */
require_once '../Classes/PHPExcel/IOFactory.php';

$objPHPExcel = PHPExcel_IOFactory::load("excel2007.xlsx");

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

PHPExcel does not have an XML reader, mainly because PHP itself provides a variety of readers for XML data. You could easily create a blank PHPExcel object, use simpleXML or any other PHP XML reader to read the file and populate the PHPExcel object, and the save it to xls.

Yes I could do this. But my catch is that I manualy create xml formated excel file with pivot table in it. As you know phpexcel doesn't have pivot table support. Because my file is 40Mb big I am searching for a way to write xml into biff. As I see on the web there isn't any php library that could do this.

We could write an XML reader, that's relatively straightforward.

But until we have implemented pivot table support in PHPExcel, that would be lost.

'fraid I don't know of any PHP libraries that could handle this (without using COM and Excel itself), though if you can call OpenOffice using the command line, then that could handle the conversion
