Hi,
If you want to export the field "product url" of your products, you can do a product export in your HikaShop backend.
This field is the value if fills yourself.
If you want to export the all final product urls, it won't be possible for HikaShop to do such job. At this moment I will recommend you to use a web-crawler in order to find all urls.
