How CSV Import Checker for Shopify reaches a result

The CSV checker runs 61 focused checks in your browser. It keeps Shopify-documented behavior separate from conservative safety checks created by One Purpose Tools.

Shopify-documented rules link to their sources. Independent safety checks are labeled separately.

How findings are classified

Shopify-documented

The finding is based on official Shopify documentation. The result includes a direct source link.

Independent safety check

The finding is a conservative product check, not an official Shopify validation rule.

What this tool cannot guarantee

The checker cannot reproduce every Shopify import decision, app behavior, or store configuration. No result guarantees that Shopify will accept an import. A product missing from a proposed CSV is not reported as deleted, and uncertain product or variant matches are never guessed.
