Renaming the tabs in single product view of woocommerce products is not that hard to do. Just adding a filter will do the trick. You can rename any tabs there. I am just showing you here one example so that you understand what I meant. Just check the below code .
Just customize the code according to your need. Here you see I have renamed the description tab with “Full Description” . You can do your own.
Same way other tab can be renamed .
