I'm having a problem using this function and I'd like u to help me.
I have a sheet filled with data until the column "AL". What I need is to get this value automatically, but when I do this:
$latestTemplateColumn = $objPHPExcel->getActiveSheet()->getHighestDataColumn();
The index of the sheet I want to get is '0' and the $latestTemplateColumn returns 'C'.
Do you have any idea of what I could possibly be doing wrong?
