[Решено] How we can export and import products in a csv/xlsx format so we can translate them

Hello, we have purchased WPML and we want to translate woocommerce website. Our question is how we can export and import products in a csv/xlsx format so we can translate them. We are familiar with wp all export/import but our main concern is that the website is already live and from what we understood the method/tutorial you have listed on your youtube is only for new websites since it needs to reimport everything from scratch. We want to know how we can do this in a live site where we have a current main language (Greek) and we want to add few more.
