Make Shopify handles ready to import

Generate clean handles in bulk, then validate or repair a product CSV in this browser. Your file is never uploaded.

Checks CSV structure and product handles, preserves variant rows, and fills only unambiguous blank handles. Review the result before importing; this does not validate every Shopify field.
