Shopify CSV structural preflight

Check one non-sensitive Shopify product CSV for supported import-blocking and review conditions.

Verified boundaries

One file, maximum 10 MB and 25,000 rows. No sensitive data, fuzzy identity matching, ambiguous merging, or third-party acceptance guarantee. Source evidence is preserved and exceptions require review.

What to check

A preflight checks encoding, supported headers, row structure, handles, variant relationships, and explicitly testable required values before import.

Safe next step

The customer retains the Shopify import. The service does not access a store, overwrite products, or guarantee Shopify acceptance.
