What the fixer checks
Upload the same XLSX file Amazon processed and, when available, the processing report from that submission. SKUFix keeps workbook structure and report evidence together instead of treating every message as generic advice.
- Workbook archive safety, readable worksheets, and a likely data table.
- Missing, duplicate, and whitespace-normalized seller SKUs.
- Parent-child references, cycles, themes, and repeated variation values.
- Report codes, SKUs, attributes, rows, columns, and explicit cell addresses.
- Template valid-values evidence and likely template mismatches.
What gets repaired automatically
Safe repair means the replacement is deterministic from the file and rule. Trimming surrounding whitespace is a typical example. Product facts, catalog choices, and ambiguous variation decisions are not safe replacements.
Free diagnosis
Review the finding, SKU, worksheet, cell, original value, proposed value, confidence, and repairability before generating a file.
Verified repair
The output is reopened and compared with the source to confirm intended changes and detect unrelated edits.
Boundaries that protect the seller
- SKUFix never invents brand, identifier, product, compliance, or variation facts.
- Amazon-side catalog conflicts remain seller or Seller Support decisions.
- The repaired workbook is never uploaded to Seller Central automatically.
- The current scope is unencrypted Amazon.com US XLSX inventory workbooks.
Where to go next
- Use the Amazon error library when you already know the processing-report code.
- Use the report analyzer when the main problem is mapping report messages to the workbook.
- Read the repair options guide when deciding between software, manual work, a freelancer, or an agency.
