You can use the Product CSV to add ASINs to your product data in bulk, making it faster to list products on Amazon. By default, the Product CSV does not include an ASIN column, but you can add it to your catalog with just a few steps.
This will add ASIN as an attribute for all products in your catalog, and it will also appear as a column in the Product CSV. You can then export the CSV and bulk-add ASINs directly in the spreadsheet.
Add the ASIN field
Go to your Products page and select any product.
Under the Product Info tab, select Add Product Identifier and choose ASIN from the list.
Enter the ASIN and select Save.
This adds ASIN as an attribute across your entire product catalog and adds it as a column in your Product CSV. From there, you can export the CSV and add ASINs for all of your products directly in the spreadsheet.
