Troubleshoot Amazon bulk upload errors by failure stage

Start with the stage that failed

An Amazon bulk upload can fail before the workbook is accepted, after individual rows are processed, or after a value reaches Amazon's catalog checks. Those stages require different evidence. A file-format rejection points to workbook structure. A processing-report row points to a SKU or attribute. A catalog conflict may require seller evidence or Amazon Support instead of another spreadsheet edit.

Record the upload time and preserve the exact workbook before making changes. Download the report for that submission when it is available. Mixing a newer workbook with an older report can create convincing but incorrect row and cell matches.

• Keep the original workbook unchanged.
• Pair the report with the upload that produced it.
• Note whether the whole file failed or only certain records failed.
• Capture the error code, SKU, attribute, row, and message.

Classify the evidence before choosing a fix

Structural evidence includes unreadable sheets, duplicate headers, missing data tabs, encrypted workbooks, or columns that do not match the expected template. Row evidence includes a seller SKU, record number, attribute, or explicit cell address. Catalog evidence includes existing ASIN values, brand authority, identifier ownership, eligibility, or policy decisions that the workbook cannot settle.

A safe repair has one replacement that follows directly from the file and rule. Trimming surrounding whitespace is a typical example. Selecting a product type, brand, identifier, variation theme, or compliance value is not deterministic unless the seller supplies and confirms the value.

Use the shortest valid repair path

Repair the workbook when the evidence identifies a deterministic cell change. Use the current template when required columns or allowed values are absent. Ask the seller when the correct value depends on product truth. Escalate to Amazon Support when catalog authority or policy prevents a file-only correction.

Resubmit only after reviewing the proposed changes against the original. A corrected workbook should preserve formulas, formatting, hidden sheets, and every unrelated cell unless a deliberate conversion is required.

• Apply only confirmed changes to a separate copy.
• Reopen the output and verify every intended cell.
• Compare the source and output for unrelated edits.
• Keep the report and repair summary with the resubmission.

Do not turn repeated errors into repeated guessing

If the same error repeats across many rows, group the findings by cause before editing. One missing parent, one invalid theme, or one outdated template can create dozens of messages. Fixing each message independently wastes time and can hide the shared cause.

SKUFix groups deterministic findings, seller decisions, template requirements, and support issues so the seller can resolve the common cause once and review the affected rows together.
