If you don't update too often your products, you could even do it manually by exporting the products in Hikashop, editing the CSV in excel to rename the columns and remove the unneeded ones and that should get you going.
The main issue will be the URL column. You would have to edit the "export" file of the view "product" to add a URL column and generate the values. or do it with a excel formula to generate all the URLs based on the product_id column: index.php?option=com_hikashop&ctrl=product&task=show&cid=XXX
