About Catalogr

Catalogr is a technical tool designed to convert large supplier product files into usable Amazon identifiers.

It focuses on a single task: reliably mapping barcodes (EAN, UPC, GTIN) to existing Amazon ASINs, at scale.

What Catalogr is built for

Many supplier catalogs contain tens or hundreds of thousands of products. Manually identifying which of those products already exist on Amazon is slow, error-prone, and difficult to automate.

Catalogr is built to handle this step in a clean and repeatable way.

How it works

No manual formatting is required. Files are processed in the background.

Data scope and limitations

Catalogr does not analyze, score, or interpret products.

Current status

Catalogr is currently in beta.

The service is free to use during this phase, with background processing and no payment required.

Additional features may be introduced gradually.
