What Shopify merchants say
Reviews from the Shopify App Store, quoted as written.
★★★★★
We have no prior knowledge and the app makes its extremely easy to navigate the complex world of EANS, GTINS etc. Support is also 5 star.
GS1 Assistant review, March 2025
★★★★★
I needed urgently to create GTIN code to our older stock (600 SKU), which would else be a nightmare, since GS1 has changed its layout of the bulk upload files. This App saved me 2 days of work! So I do recommend it
