CSV Preflight for Shopify

Shopify's product importer throws errors like "Handle: is invalid" pointing at the wrong line — and you lose an afternoon hunting for it.

Check your product CSV here before you import. Every error and warning, with the real row and a plain-English fix — then download a corrected, import-ready file.
