However, we don’t have a CSV or XLS exporter yet, although there are several export plugins available that integrate with ours. For example, you could try a pretty good free plugin called Advanced Order Export For WooCommerce from AlgolPlus. Another option (paid) that also collects the fields of our invoices and is a little more intuitive is: Store Exporter Deluxe for WooCommerce by Visser Labs.
