Overview

When uploading inventory files to Amazon Seller Central, sellers may encounter errors that prevent their product listings from going live or updating correctly. Understanding how to identify and resolve these errors is essential to maintaining accurate catalog data and avoiding disruptions to your selling operations. Amazon provides processing reports that detail exactly what went wrong, making it possible to diagnose and fix issues efficiently.

Key Points / What Sellers Need to Know

• Processing reports are your primary diagnostic tool - After every inventory file upload, Amazon generates a processing report that lists each error by row and field, allowing you to pinpoint exactly where problems occurred in your file.
• Side-by-side review is recommended - Open your original inventory file alongside the processing report so you can cross-reference error messages with the specific data entries that triggered them.
• Errors do not necessarily reject the entire file - Amazon processes inventory files on a row-by-row basis, meaning valid rows will still be accepted even if other rows contain errors.
• Field formatting is the most common cause - Mismatched data types, missing required fields, and incorrect value formats account for the majority of upload failures.
• Re-upload only corrected rows - Once you fix the errors, you can re-upload a file containing only the corrected rows rather than re-submitting the entire file.

Common Error Types

Inventory file errors generally fall into several categories. Missing required fields are among the most frequent, where mandatory attributes like SKU, product title, or price have been left blank. Data format errors occur when a field expects a specific format — such as a numeric value for price or a date in a particular structure — and receives something unexpected. Value validation errors happen when an entry does not match Amazon's accepted values for a given attribute, such as an invalid condition type or an unrecognized category node. Duplicate SKU errors arise when the same SKU appears multiple times within a single file or conflicts with an existing listing in your catalog. Understanding which category your error falls into helps you resolve it more quickly.
