Hello,
Sorry for my late answer. Actually, the custom columns are well present in the export file when I check that field that you show in your reply.
But the other way round does not work when I try to import in WooCommerce new products with data in these columns.
Thank you in advance for your help and feedback, as we have a very long list of products to update it would be a nightmare to do it without using the import function.
Best regards
