Upload new products to a zencart site with easypopulate - confirm the template and structure to do this

Hi If you know zencart you will find this easy. I have a coder who built a site on zen cart and populated the products. We have more products to go on now, and it has easy populate. What I dont know is if the .csv I am attaching can go on as is, or if it needs editing to a specific format. So I am attaching. the new product range to be added to the site the current inventory for all the products on the site, including the new products the current details minus attributes, downloaded from the live site. Job is simply this, ensure the products - all of them go on the site urgently, and tell me how you did it. You MUST use zencart to upload the .csv. Site uses a non custom zencart integration. I can give you full FTP, PHPMyadmin and control panel and zencart login, although I expect zencart login will suffice. This is urgent, I need it done tonight. PS the product images are already uploaded.
