Catalog health
Find duplicate SKUs and barcodes before they break Shopify catalog workflows
A before-and-after workflow for duplicate identifiers in supplier files and live Shopify catalogs.
Why duplicate identifiers matter
Duplicate SKUs and barcodes can make inventory work, feeds, reports, and supplier updates harder to trust.
Before import
Use GrowthLine File Cleaner to check supplier files before uploading them to Shopify.
After import
Use GrowthLine Catalog Doctor to scan the live catalog and find duplicate identifiers already in Shopify.
Review before fixing
Merchants should decide which product or variant should keep each identifier before applying any changes.
Use both tools when needed
File Cleaner helps prevent duplicate data from entering Shopify. Catalog Doctor helps find duplicate data that is already live.
