Missing products.
Products present in only one of the two supplied exports.
Free early release
Merchant Sync Check.
Compare Shopify and Google Merchant Center product exports before catalog differences reach shoppers or paid campaigns.
The checker finds missing products, duplicate identifiers, price and availability differences, and values that cannot be compared safely. The application runs separately from this page so catalog contents stay outside DIGITO site analytics.
Merchant Sync Check is free to use during this early release. Optional PayPal support does not unlock features or change access.

What it checks.
One comparison turns two export snapshots into a focused issues list and a formula-safe CSV.
Duplicate identifiers.
Repeated SKU, barcode, or GTIN values isolated before comparison.
Price differences.
Comparable prices that differ without silently converting currency.
Availability differences.
Confident in-stock and out-of-stock values that do not agree.
Unsafe comparisons.
Blank keys, mixed currencies, malformed rows, or ambiguous inventory data.

Browser-local processing.
The application processes selected files and comparison results in browser memory. It has no upload endpoint, catalog database, account, AI service, advertising scripts, or application analytics. The app host may still receive ordinary request metadata needed to serve the page.
This indexable product page uses DIGITO's normal aggregate site analytics. The linked application is a separate surface and does not load them.
Supported exports.
- Shopify product CSV using current or supported legacy headers.
- Google Merchant Center product data in CSV or TSV format.
- Up to 10 MB and 50,000 data rows per file.
- SKU to a selected Merchant identifier, or barcode to GTIN.

Need help fixing what you found?
DIGITO can review the generated issues report and scope the cleanup. Original Shopify and Merchant Center exports are not required unless a separate project channel is agreed.
See DIGITO services →Questions.
Do catalog files upload to DIGITO?
No. The isolated application reads the selected files in browser memory. It has no catalog upload endpoint, account, or catalog database. Ordinary hosting request metadata can still be processed when the application page loads.
Which files are supported?
Use a Shopify product CSV and a downloaded Google Merchant Center CSV or TSV with compatible product fields. Each file is limited to 10 MB and 50,000 data rows.
How are products matched?
Choose Shopify SKU matched to a Merchant identifier, or Shopify barcode matched to Merchant GTIN. Values are trimmed and matched exactly with case preserved. There is no title matching, fuzzy matching, or identifier rewriting.
Is Merchant Sync Check free to use?
Yes. Merchant Sync Check is free to use during this early release. Optional PayPal support does not unlock features or change access.
Does the checker change Shopify or Merchant Center?
No. It compares only the supplied export snapshots. It does not modify either platform, replace a direct integration, or guarantee Google Merchant Center approval.
Independent product.
Merchant Sync Check is an independent DIGITO product. It is not affiliated with, authorized by, sponsored by, or endorsed by Shopify or Google. Shopify, Google Merchant Center, Google Shopping, and related marks belong to their respective owners.
