Catalogr

Convert supplier barcode catalogs into ASIN mappings using the Amazon SP-API Catalog Items endpoint.

What Catalogr does

• Ingests supplier .xlsx files containing EAN, UPC or GTIN
• Normalizes codes to GTIN-14
• Resolves matching ASINs via Amazon SP-API (Catalog Items)
• Exports two files: mapped.csv (GTIN to ASIN) and unmapped.csv
• Displays run metrics: duration, cache hits, API calls

Typical workflow

1. Upload your supplier spreadsheet (.xlsx)
2. Select a marketplace
3. Download mapped and unmapped results

Data usage and compliance

• Catalogr currently uses the Amazon SP-API Catalog Items endpoint only
• No access to seller account data
• No access to pricing, fees, offers, sales, or Brand Analytics data
• No cross-user data aggregation
• Technical GTIN to ASIN cache stores product identifiers only
