What it catches
Duplicate option combinations under one Handle, mismatched option names, duplicate SKUs, blank option values, and variant rows that need review before import.
Shopify variant preflight
Find duplicate Shopify variant option combinations before import.
Check whether rows under the same Shopify Handle repeat the same Option1, Option2, or Option3 values. Repeated combinations such as Size Small and Color Blue can make Shopify or Matrixify overwrite, merge, or reject variant rows.
Why it matters
Migration files often contain repeated Size, Color, Material, or Default Title rows. Catching them before import reduces manual cleanup after a failed catalog upload.
Safe outputs
Export Issues CSV, review rows, field mapping, blocked rows, and a Markdown report without uploading the CSV or connecting to a Shopify admin.
Best fit
Shopify migration freelancers, ecommerce agencies, and store owners preparing Matrixify-ready product CSVs from WooCommerce, supplier catalogs, or older Shopify exports.
