Hello Bev,

I am really sorry for the delay of this reply as it is a weekend for us here.
Correct me if i getting wrong meaning of your first post, do you mean that export all the komento comment then you would like to clean all the comment from your component?
If yes, actually that is not possible export the comment from Komento to Excel or another type of document, but you can just export the tables of prefix_komento_comments from your phpmyadmin, after you clean all the comment from your component, then you import back "tables of prefix_komento_comments" in your database.
Notice* : Remember when you do this before backup all your data from your database.
