Why Commerce Guardian
A smaller, safer step between a warning and a feed change.
Merchant Center tells you what needs attention. Commerce Guardian checks whether the exact product row already contains the missing value, then creates a supplemental CSV you can review.
Conservative by design
IDs must match exactly. The tool never guesses a brand from a title, repairs identifiers, or invents product data. Ambiguous cases stay marked for human review.
Local by design
The scanner runs in your browser. There is no catalog upload, backend, account or production AI. You remain in control of the source files and the final import.
Built for verification
Every result shows its status, source column and reason. The output contains only the product ID and safe attributes, making it easier to inspect before use.
