Hello Terry,
this would depend on how the products export works on WooCommerce.
You can find a guide about importing/exporting products in WebSite X5 here:

If Woocommerce manages products similarly, and generates a file with a similar structure, it could be possible to adjust this file to follow WebSite X5's format for this.
