How to Fix Common Spreadsheet Errors When Uploading Coupons in Bulk
Comprehensive guide to diagnosing and fixing common errors when bulk-uploading coupon spreadsheets in Seller Central, covering ASIN validation, date rules, title formatting, budget limits, and overlap conflicts.
Overview
When Amazon sellers upload coupon spreadsheets in bulk through Seller Central, the system processes the file and generates a status report that flags any errors. Understanding these errors and knowing how to resolve them quickly is essential for sellers who rely on coupons as part of their promotional strategy. This guide breaks down every common spreadsheet upload error and provides clear steps to fix each one.
Key Points / What Sellers Need to Know
- Download the status file after every upload - Amazon generates a detailed report showing the success or failure of each coupon row in your spreadsheet, so always review it before assuming your coupons are live.
- Only child ASINs are accepted - Parent ASINs cannot be used in coupon spreadsheets. Each coupon supports a maximum of 2,900 child ASINs.
- One active coupon per ASIN at a time - If an ASIN already has a scheduled coupon during an overlapping period, the new coupon will be rejected.
- Spreadsheets are capped at 100 coupons - You cannot enter data beyond row 119 (header row plus 100 coupon rows), so plan your uploads accordingly.
- Budget limits apply - Coupon budgets must be at least $100 and cannot exceed $10,000,000 per coupon.
- Coupon scheduling has strict date rules - Start dates cannot be in the past, and coupons can be created up to 180 days in advance.
ASIN-Related Errors
Several of the most common upload failures relate to ASIN issues. First, every value in column A must be a valid ASIN. If you are listing multiple ASINs separated by semicolons, double-check that each one is correctly formatted and exists in the Amazon catalog. Second, remember that only child ASINs are permitted. Adding a parent ASIN will cause the entire coupon to fail, so verify your ASIN type before uploading. Third, each coupon is limited to 2,900 child ASINs. If your promotion covers a larger catalog, you will need to split the ASINs across multiple coupons. Finally, duplicate ASINs within a single spreadsheet will cause the upload to fail entirely, so remove any repeated entries before submitting.
