Checked as you type
Duplicate SKUs, invalid characters, missing or negative prices, empty options and repeated values are flagged the moment they appear.
Catalog validation
Product catalog validation: import with confidence.
A failed import costs an afternoon. VariantFlow checks your catalog as you build it and will not export a file that is not ready.
Plain-language issues
Every problem is listed in words a person can act on, and the affected rows are highlighted in the table.
Advanced checks on Pro
Zero prices, prices far from the rest, extra spaces, inconsistent capitalization, very long SKUs and Shopify’s 2,048-variant limit.

FAQ
Frequently asked questions
What stops an export?
Errors do: duplicate or invalid SKUs, missing or negative prices, a missing title and empty options. Suggestions from advanced validation never block you.
Is validation included in the Free plan?
Yes. Core validation is in every plan. Advanced validation is part of Pro and Scale.
Does it check my existing store?
No. VariantFlow checks the catalog you build or import in the workspace. It never connects to your store.
