Hi Product Hunt!

I built Supplier Catalog Normalizer for a recurring ecommerce problem: supplier CSV/XLSX files rarely use the same structure.

One supplier may call a field “SKU”, another “Item #”, another “Product Code”. Titles, prices, descriptions, image URLs and categories may also live in different columns or sheets.

The tool lets you:

choose the source sheet and header row;
review and edit detected column mappings;
exclude blank or non-product rows;
export a normalized catalog;
export a Shopify-format CSV;
download diagnostics for rejected rows and mapping decisions.

I wanted the transformation to stay visible rather than becoming a black box, so mappings are always reviewable and editable.

It is designed as a focused first step before importing supplier data into an ecommerce catalog.

The current public version is free and does not require registration.

I’d be interested in feedback from people who regularly work with supplier feeds, product catalogs or marketplace imports.
