Common errors and fixes

Invalid or blank Handle values

Shopify uses Handle to group product rows, so blanks, spaces, uppercase variants, and special characters can split or reject products.

Use lowercase handles with hyphens, keep the same handle for all variant rows of one product, and rerun the checker before import.

Duplicate variant SKUs are reported

Two product rows may share the same Variant SKU because of a copy-paste mistake or a missing variant option.

Fix accidental repeats in the source CSV and only keep duplicate SKUs when your Shopify workflow intentionally allows them.

Price, status, or image URL warnings appear

Shopify imports expect clean numeric prices, valid product statuses, and image URLs that can be fetched during import.

Rewrite prices as plain numbers, use accepted status values, and test image URLs in a browser before uploading.

When to use Shopify Product CSV Preflight Checker

  • You are checking files before an upload, import, share, or delivery.
  • You want to confirm the result before sending it to another system.
  • You need a copied result, downloaded file, or report that can be reviewed outside the page.

FAQ
