I've magento version 18.104.22.168. It's easy to import/export simple product however a little tricky is configurable products. I'm able to import configurable product too but since I don't know what is the heading name and values for the super product attributes I'm unable to get the different select options. I'm attaching the backend of the Super product attributes. If someone can simply write here what heading I must use and how to give it's values in multiple, it would be wonderful.
