I have been looking for this very plugin for years

Yay! Finally a plugin that not only imports all of your etsy products to woo-commerce, but also automatically selects the main photo and keeps the correct format. You can have variations and it’s easy to use.
I also appreciate the very quick responses I received in the support forum.
I had nearly 500 products to import, and once my server was able to handle the massive upload, it worked like a charm.
I also like that, in the future, when I upload products, it will detect duplicates.
