Flat-file validator

Catch workbook problems before the next failed upload.

Run deterministic structural and row-level checks without changing the original file.

What SKUFix checks

  • Likely data worksheet and header row.
  • Missing and duplicate seller SKUs.
  • Leading or trailing whitespace in mapped fields.
  • Broken parent-child references and inconsistent variation themes.
  • Duplicate headers and unsupported workbook structure.

What happens next

  1. Upload an unencrypted Amazon.com US XLSX inventory workbook.
  2. SKUFix validates the archive before opening the workbook.
  3. The free diagnostic groups safe repairs, seller-input issues, and support issues.
  4. Only selected cell changes are applied to a separate output file.

Safe automation only

High-confidence deterministic fixes are selected automatically. Product facts, catalog choices, and support issues are never guessed.
