CSV2Store imports product catalogs into Shopify from a CSV, XLSX, TSV, or JSON file, including messy platform exports. It auto-detects encoding and delimiters, then uses AI to map each column to Shopify fields such as title, price, SKU, variants, and images, with confidence scores you can review and override. It normalizes European decimals, strips unsafe HTML, and groups rows into multi-variant products. A validation report flags missing fields, duplicate SKUs, and bad prices before import.
