QlikSense ExportData API export to CSV has the limitation of 5 millions cells. This is a big feature gap for our customer. Our clients would like the Qlik Sense to also allow more than 5M cells to be exported into CSV. Qlik View allows exports up to 5 million rows, so QS should allow at least the same number of rows to be exported.
This is not something we will deliver as part of the export capabilities. Qlik offers data management solutions that should address the needs to transfer large data volumes in more robust and capable ways.
