Can I create a duplicate row for each line item quantity in the order export?
Yes, you can!
In the Order Data Settings, under the Extra Options section, just select the checkbox Create a duplicate row per line item quantity.
With this option enabled, EZ Exporter will duplicate the row based on the ordered quantity of each product. So for example, if a customer orders 10 of product SKU 1234, in the CSV export you will then see 10 rows for that line item and the quantity will be changed to 1 (as opposed to 1 row for that line item with quantity set to 10).
