Merchant Feed Check vs. DataFeedWatch
Two different shapes: DataFeedWatch connects to your store, transforms your product feed with rules you build, and exports it to many advertising channels — an ongoing subscription account. This page is a free, no-account checker for one question — does a feed you already have conform to Google Merchant Center's and Meta Catalog's own published product-data specification — before it syncs.
What each tool is for
DataFeedWatch is product-feed management software, sold under an ongoing subscription account to e-commerce sellers and agencies. It connects to your store or feed source, lets you build transformation rules — title templates, category mapping, attribute enrichment, custom labels — and exports the optimized result to many advertising and marketplace channels. Setting it up means creating an account, connecting a data source, and configuring channel-specific export templates, not a one-off check. DataFeedWatch's own site is not reachable from this session to confirm today's specific plan names, product-count tiers, or pricing, so only its well-documented category and identity are stated here: nothing about it is invented, and no dollar figure for it appears on this page.
This checker does none of that. It does not connect to a store, build transformation rules, or export a feed anywhere. It takes a feed you already have — CSV, TSV, or JSON, pasted or loaded from a file — and reports, item by item, exactly what would fail Google Merchant Center's or Meta Catalog's own published product-data specification: missing required fields, invalid GTIN/MPN checksums, malformed prices and availability values, and known promotional-text disapproval triggers. It runs free in any browser, and the same logic ships as a zero-dependency Node CLI you can run as a CI gate right before your feed generator syncs. No account, no upload, nothing stored.
| Question | Where to answer it |
|---|---|
| I need to connect my store, transform a feed with rules, and export it to many advertising channels. | DataFeedWatch, or a comparable feed-management platform. |
| I want to know whether the feed I already have would get items disapproved, before I sync it. | This checker — free, instant, no account, nothing uploaded. |
| I want the same check to run automatically before every deploy, as a CI gate. | This checker's zero-dependency CLI (cli.mjs), run against the file your generator produces. |
| I need channel-specific field mapping, category rules, and multi-channel export. | DataFeedWatch, or a comparable platform — this checker has none of those features. |
| Why do products actually get disapproved, beyond a failed check? | This checker's disapproval-reasons page. |
| Do I need an account or a connected data source to use the tool? | This checker: no. DataFeedWatch and comparable platforms are sold through an ongoing account. |
A seller running feeds to several channels gets different value from each: DataFeedWatch (or a comparable platform) for building and routing an optimized feed day to day under an ongoing subscription, and a free checker like this one for an instant, no-login answer to whether a feed conforms to the published spec, wired into CI if you want it there. This page's own report is a deterministic read of the feed you loaded, not a guarantee that Google or Meta will approve any specific listing.
This tool needs no account and no sign-in: the browser page parses a pasted or locally loaded file entirely in your own browser, and the CLI reads only a local file. Neither ever sends your feed anywhere.
Common questions
Should I use this checker or DataFeedWatch?
They do different jobs, and a seller running feeds to several channels will likely end up touching both. DataFeedWatch is product-feed management software, sold under an ongoing subscription account: it connects to your store or feed source, lets you build transformation rules (title templates, category mapping, attribute enrichment), and exports the result to many advertising and marketplace channels. Setting it up means an account, connecting a data source, and configuring channel-specific export templates, not a one-off check. DataFeedWatch's own site is not reachable from this session to confirm today's specific plan names, product-count tiers, or pricing, so only its well-documented category and identity are stated here: nothing about it is invented, and no dollar figure for it appears on this page. This checker does none of that. It does not connect to a store, transform a feed, or export anywhere. It takes a feed you already have -- CSV, TSV, or JSON -- and reports exactly which items would be flagged against Google Merchant Center's and Meta Catalog's own published product-data specification: missing required fields, invalid GTIN/MPN checksums, malformed prices, and known promotional-text disapproval triggers. It runs free in any browser or as a zero-dependency CLI, keeps no account, and nothing you load is uploaded. A seller building and routing feeds to many channels day to day is better served by DataFeedWatch or a comparable feed-management platform; a seller who wants to know whether a feed conforms to the spec before it syncs, or wants that check wired into their own CI pipeline, is in the right place here.
