Hi onmountain,
From this post (https://forum.scriptcase.net/forum/main-category/main-forum/75883-export-on-xls-or-csv-very-slow) you seem to have a lot of experience with PHPExcel. I’m stuck in a debugging loop trying to read a large xlsx file in chunks. It’s not able to go beyond the interface instantiation statement. Do you have a clue why this (https://forum.scriptcase.net/forum/main-category/main-forum/83978-reading-large-excel-files-using-chunks-with-phpexcel-in-sc) is not working?
Thank you
