I currently own the WooCommerce Checkout Field Editor extension and need to export customers, orders and the custom fields from Checkout Field Editor as a .csv. If I purchase the Order/Customer CSV Export extension can I export the custom fields from Checkout Field Editor? I have a feeling I can from this link under "Adding custom meta fields" (http://docs.woothemes.com/document/ordercustomer-csv-exporter/) but I don't want to purchase the extension unless I know for sure. Plus, I can't tell from the "Adding custom meta fields" instructions if I add the code in the functions.php file. Please help. Thanks.
