CSVwise cleans messy product CSVs before you import them into Shopify. Upload a file and it flags the problems that break imports: malformed prices, invalid weights, duplicate handles, inconsistent tags, and formatting errors, then fixes them automatically. Cleaning runs in your browser. Only your column names and up to 5 sample rows are sent to an AI provider for the optional column-mapping step. It also checks your file against the products you already sell. Download an import-ready CSV.
