Catalog Sentinel, a browser-local product-feed preflight
A free beta that checks CSV, TSV, TXT, and common Google Shopping XML feeds for product-data problems and produces a row-level action list.
Field notes
Catalog Sentinel reads one catalog file at a time and turns deterministic feed checks into an issue ledger tied to source rows and fields. Its beta accepts CSV, TSV, TXT, and common Google Shopping XML, with limits of 10 MiB and 10,000 products. The visible example flags a price written as “19.99” because it lacks a three-letter currency code, then recommends a concrete correction. The page says processing remains in the browser session and the original file is neither changed nor saved.
