Paste or drop a product CSV. This runs entirely in your browser - the file is never uploaded anywhere. It flags the problems that actually stop a Shopify import or corrupt variants: duplicate SKUs, duplicate handles, missing required fields, variant rows without an option value, bad prices, and rows that disagree with the product row above them.
For supplier exports, migrated catalogs, and files with thousands of rows I offer a fixed-scope import-prep job: a deeper pass than this page (cross-row variant consistency, image URL checks, weight and quantity sanity, collection tags, metafield columns), returning a ready-to-import CSV plus a written list of what I changed and why.
$25 flat - one file up to 1,000 rows, delivered within 3 business days. If I can't process the file, you don't pay.
