Convert supplier catalogs into Amazon ASINs instantly
Upload your supplier catalog. Get every ASIN in minutes.
Who it's for
Built for Amazon wholesale and retail arbitrage sellers who source from supplier catalogs.
If you've ever spent hours copy-pasting barcodes into Amazon search, Catalogr was made for you.
What Catalogr does
Stop looking up ASINs one by one.Wholesale Amazon sellers receive supplier catalogs with thousands of barcodes (EAN, UPC, GTIN).
Finding the matching ASIN for each product manually takes days.
Catalogr does it in minutes.
- Upload your supplier spreadsheet (.xlsx)
- Select your Amazon marketplace (EU supported)
- Download mapped.csv with every GTIN → ASIN match
- See exactly what couldn't be matched (unmapped.csv)
Typical workflow
- Upload your supplier spreadsheet (.xlsx)
- Select a marketplace
- Download mapped and unmapped results
1,000 barcodes per minute - and it gets faster over time.
Catalogr's shared cache means every resolution improves the database for all users.
The more sellers use Catalogr, the faster and more complete your results become.
First run on a fresh catalog : ~1,000 GTINs/min
Repeat run or cached catalog : instant
