great! one last clarification: is the generated EAN “valid”? I mean, if I use that generated EAN to search for the corresponding product on amazon (yes, amazon has this feature), do I find it? do they match?
Thank you very much for your reply.
I realized that i explained myself very badly.
My problem is neither with exporting nor with importing,
my problem is that i have a long list of products — without EAN — in my woocommerce, and I have to add the EAN for each product, but i certainly can’t do it by hand
