Preflight findings
A clear report is not a guarantee. Review the file, back up your store, and run a test import.
Optional feedback
Tell us what helped, and what we missed.
If you used the checker on a product CSV problem, record any finding you could act on and any import failure it did not catch. A clear checker report can still miss a real failure.
