Independent tool for Shopify-format product CSVs. Not affiliated with or endorsed by Shopify.
Free version: up to 25 products per run. Products are counted as unique URL handles in the proposed import (plus any handle-less rows with a title). Catalog Check Pro removes the cap for a one-time US$49 payment, with no subscription. Refunds on request within 14 days. Buy Catalog Check Pro — US$49 Checkout is hosted by Stripe. Card details are never entered on this site.
File contents are processed only in this browser. No uploads, network requests, analytics, or saved catalog data. Image URLs are never fetched.
Match this setting to your intended Shopify import. Unchecked means existing matching products are ignored. Missing products are never interpreted as deletions.
Choose two files, or try the fictional demo.
Review aid, not a safety guarantee. Back up your store and test a small subset in a development store. This tool does not import, correct, or modify your files. A clean report does not mean an import is safe.

Selected product fields and matched variant SKU/prices only. Not a complete import simulation. Blank continuation rows are not treated as product-field clearing.
