You need to push products to your WooCommerce store after importing. You can edit products or image before pushing it to your store.
You can pick a product or a few products to push at the same time. The maximum number of products is five because WordPress has limited time to input.
Push single product
Push bulk products
Note: Please do not change the product SKU in WooCommerce because it will make the error when orders fulfillment and sync products.
