The Inventory Loader is a template you can use to add your listings to ASINs already on Amazon. With this file, you don't have to fill in all the product information you would normally need for a new product detail page.
Here are the steps you need to follow:
1. Login to your seller central account and click “Inventory>Add Products via Upload”
2. Scroll down to the bottom of the page and click “Inventory Files” tab. Afterwards, click “Inventory Loader” under the file names.
3. Download the inventory loader template from the opening page.
