Workflow guide
Use this workflow before a listing upload when the source file is already in spreadsheet form. It separates the upload into three checks: flat-file row quality, parent-child variation structure, and image readiness. The goal is to fix obvious file and image problems before they become rejected uploads, broken variation families, or manual cleanup in Seller Central.
Catch file and image problems before a Seller Central upload creates listing errors or variation cleanup work.
Amazon sellers, catalog operators, VAs, and listing assistants preparing spreadsheet-based catalog updates.
Missing SKU, blank price, invalid quantity, unsupported update action, and risky image URL values are easy to miss in a large template. The flat-file report turns those issues into row numbers.
Parent-child uploads can fail when child rows point to a missing parent, variation themes are inconsistent, or the same option combination appears more than once.
A product photo can look fine in a folder while still being too small, the wrong file type, transparent, or not ready for zoom. Image checks should happen before the final flat-file pass.
The safest first pass is a file-first check. Paste the flat file exactly as it will be handed off, including the header row, then review row-level errors before making edits. This avoids the common mistake of fixing one visible Seller Central error while leaving other rows untouched.
Variation mistakes are expensive because they can create listing cleanup work after upload. Run parent and child rows through the variation checker before spending time on images or copy. The report should make missing parents, repeated child combinations, and incomplete option fields visible.
Images should be checked as local files, not just as filenames in a spreadsheet. The image report gives the listing assistant a concrete list of files to resize, flatten, or replace before the final upload package is assembled.
A CSV report with row numbers, field names, and issue notes for SKU, price, quantity, update action, image URL, and variation-related values.
A focused report for missing parent SKUs, duplicate child option combinations, and incomplete variation fields.
A file-by-file image report covering dimensions, type, transparency risk, and zoom readiness.
Check an Amazon inventory flat file before Seller Central upload with browser-local streaming for large CSV exports.
Check parent-child variation rows before upload and find missing parent SKUs, duplicate options, and broken variation families.
Batch check product images against common Amazon image requirements and download a CSV report.
No. It is a browser-local preflight workflow. You use the reports to fix your files, then upload through Seller Central yourself.
No. It catches visible file, variation, and image risks before upload, but category-specific rules and account-specific restrictions can still apply inside Seller Central.
Start with the flat-file checker, then run the variation checker if parent-child rows are present, then check the final product images.
