Data import - List of headers?

Hi all,

Is there a list of headers and what they refer to anywhere? I’m hoping to bulk upload our products but looking at the data import tool there’s some headers I’m not sure about, and some I don’t know if I am understanding correctly.

Series, item name, item group, Item code etc. I assume one is the internal product ref/code, another is the product name that would be displayed on an invoice? But I am definitely getting a little confused.
