Remove All Products

Do you mean you want to delete all the products in your website?
Just go to the “Products” in your Dashboard and select all the products. See if it works.

I can do it that way yeah, but it would be time consuming as I have thousands of products creating in error during an import.

I just wondered if there was quicker way.

There’s a quick way via MySQL. See instructions here: https://www.kc-webdesign.co.uk/e_commerce/woocommerce-how-to-delete-all-products/
