Single Use

See every featureSupplier price lists and catalog spreadsheets rarely match Shopify's CSV template. Portaim imports them as they are: upload a CSV or Excel file, or a Google Sheets, Drive or Dropbox link. AI maps the columns to Shopify fields, splits combined values into variant options and turns image columns into a gallery. Every row is checked for what Shopify would reject, with one-click fixes.
All Merchant Product Importer creates and updates products from a file you already have. It reads CSV, Excel, and XML files, with presets for common export formats. Map each column to the matching field — title, description, price, SKU, barcode, inventory, images, tags, and options — and related rows become one product with its variants.
- 40+ validation rules catch price, weight, URL, and format errors before import
- AI column mapping matches supplier fields to store fields automatically
- Batch auto-fix resolves most issues — strips currency, converts units, normalize
- Supports CSV and XLSX files from any supplier format
- Import product catalogs from CSV, Excel, and XML files.
- Map product fields such as title, price, SKU, images, and inventory.
