CatalogWash
Catch Shopify variant CSV errors before import
Variant imports can split products, merge unrelated rows, or create broken option sets when handles, SKUs, prices, and option names are inconsistent. CatalogWash previews how Shopify will read your product to variant structure.
Duplicate Variant SKU checks
Option1/Option2/Option3 consistency
Suggested grouping that needs review
Review before export
Variant grouping can be ambiguous. CatalogWash shows likely groups and flags unsafe cases, but it does not silently merge ambiguous products for you.
