YITH WooCommerce Gift Cards allows you to export orders, customers and coupons into a CSV file.
The integration with YITH Gift Cards allows also exporting gift cards information into a .csv file.
To benefit from this integration, you simply have to install and activate the premium version of both plugins.
Then, go to YITH > Quick Export > Data Exportation tab and select the Gift Cards checkbox to export all your gift cards. If you want to, you can filter them by date and export only those generated in a certain time frame.
To learn more about the plugin settings, please, read YITH Gift Cards official documentation.
