Shelfmark takes the whole list from one CSV file. Your file is checked against your catalogue first, and each problem is named in plain English: a code already on another product, a code given to two SKUs, a variant already at the limit, a check digit that does not match. Nothing is written until you have read that list."

Shoplist has not yet found reliable public storefront evidence connecting a Shopify store to this app. This does not mean the app has no users. Some apps are new, admin-only, server-side, theme-independent, or otherwise difficult to detect from public storefront signals.


## Public callouts
- Add every extra barcode from one CSV instead of typing them one by one
- Shows the clashes, duplicates and typos before a single product changes
- Catches a code already used on another product, and names that product
- Find a product by any of its barcodes, not only its primary one
- Asks for products only, never your orders, customers or personal data
## Shopify App Store categories
- SKU and barcodes
