Free Shopify SKU Review & CSV Handoff

Last updated: July 31, 2026

Find missing or duplicate Shopify variant SKUs in an exported product CSV, document the decisions, and download a review report before an import or cleanup handoff.

The checker runs in your browser. It never invents missing SKUs or rewrites duplicates because those identifiers may already be tied to fulfillment, ERP, feed, or reporting systems.

Why check missing Shopify SKUs before an import?

Blank or repeated variant SKUs can break spreadsheet matching, inventory reporting, fulfillment handoffs, and product-feed cleanup. They can also be intentional. This checker surfaces the affected rows without pretending it knows the store's identifier policy.

What the checker will and will not change

CSV problemChecker actionMerchant decision
Blank Variant SKU valuesIdentify the affected row; write no replacement value.Assign a SKU only from the documented store, warehouse, ERP, or supplier scheme.
Duplicate Variant SKU valuesList every row sharing the value; preserve the original CSV.Confirm whether sharing is intentional and which connected systems depend on the identifier.
Prices, barcodes, images, descriptionsAdd review notes with explicit limitations.Change only fields that violate the store's actual channel or merchandising rules.

When the app is worth installing

  1. The review report contains SKU decisions or many product-data notes.
  2. You want the same checks against the live Shopify catalog instead of copy-pasting CSV rows.
  3. You need recurring audit history, monitoring, or higher scan volume after the first cleanup pass.
