Field notes
The validator runs against local CSV, TSV, or XML files rather than connecting to an ad account or uploading data. Its comparison workflow records SHA-256 hashes for the exact input bytes, reruns the same versioned rules, and can produce portable JSON or self-contained HTML evidence. The page cites limits of 25 MB and 100,000 rows, while its sample report processes 2,418 products and flags 121 issues.
