Call me crazy but this doesn't account for cell indexes or row indexes - if you look at the ss parse method of my class here - https://github.com/donatj/XLS-XML-Formula-Expander/blob/master/XXLS.php it might point you in the right direction

Hi donatj, thanks for the heads up, I do account cell index already (see line #185) but seems I forgot to check row index as well :P

Edit: this repo has been moved to http://github.com/faisalman/simple-excel-php since 3 months ago, if you don't mind please give your feedback/suggestion there.

Thanks a lot ;)
