Overview

Amazon’s Inventory Loader spreadsheet lets Professional sellers bulk‑add offers for products that already have detail pages in the Amazon catalog. By focusing only on matching identifiers such as SKU, UPC, EAN or ASIN, the file bypasses the need to re‑enter titles, images and attribute data. Sellers who need to list large quantities of existing items can therefore save hours of manual entry.

Key Points

• Professional plan required — Only accounts on the Professional selling plan can download or submit the Inventory Loader; Individual sellers see the upload option disabled.
• Targets cataloged items — The template works exclusively with products that already exist on Amazon, so you do not have to supply full product descriptions, bullet points or images.
• Ideal for simple matching — Amazon recommends the loader for straightforward one‑to‑one matches where each SKU maps to a single, already‑published ASIN.
• Limited when multiple matches appear — If a UPC or EAN returns several possible ASINs, a category‑specific template (e.g., the “Category‑Specific Inventory File”) usually yields more accurate results.
• No new product creation — The loader cannot generate brand‑new listings; it only attaches your offer to an existing detail page.

How the Inventory Loader Works

1. Download the flat‑file — From Seller Central, go to Add Products via Upload and click the Inventory Loader link. For example, a seller of kitchen gadgets downloads a file named InventoryLoaderTemplate.xlsx.
2. Populate required columns — Fill in the SKU column with your internal identifier and the “Product ID” column with a matching UPC, EAN or ASIN. If a seller’s SKU is KG‑001 and the product’s UPC is 123456789012, they enter those values in the respective rows.
3. Leave optional fields blank — Columns for title, description, bullet points, and images are optional because Amazon pulls that information from the existing catalog entry. A seller can therefore leave the “Item Name” cell empty, letting Amazon auto‑populate it from the matched ASIN.
