Catalog Preflight

What is Catalog Preflight?

Catalog Preflight is a browser-local Shopify product CSV checker. Compare a planned file with a fresh export and review missing variant combinations, inconsistent variant fields, price/Compare At Price combinations, and inventory tracking fields before importing. It never uploads a file, connects to Shopify, or changes a store. The checker is free; an optional implementation kit is available for merchants who want a repeatable workflow.
