How does AI column mapping work?

Portaim analyzes your column headers and sample data, then suggests which Shopify field each column maps to. Common columns are matched automatically, less obvious ones get AI-powered suggestions you can accept or adjust.

From messy CSV to Shopify-ready products

Import supplier product data into Shopify. AI maps columns, validates everything, and fixes issues — you just confirm.
