What this check can't tell you

It compares two files. It doesn't connect to your store, so it only knows what your export contains.
It follows Shopify's published CSV rules. Shopify can change how imports behave, and an import may act differently from what's shown here.
It doesn't check image links, collections, multi-location stock, or whether a value is correct for your business.
No warnings doesn't mean the import is safe. Keep a fresh export as a backup, and try a small test import first.
