Sku Fetch can be used to list on Shopify if you're using the Drop Ship Supplier Scraper chrome extension -

You'd need to install the chrome extension

Be logged into your Sku Fetch & Wise lister accounts.

Be logged into your Shopify admin dashboard/panel

In Sku Fetch, I'd suggest creating a new workspace for your Shopify items and configuring your settings.

Then finally, in the List & Export Settings in Sku Fetch, you would select the Lister for Single Fetch to be Shopify via Chrome Lister

The same for Big Product Fetch.

You won't be able to Batch items to Shopify.
