Import supplier CSV/XLSX files into Shopify without manual cleanup

Portaim maps supplier columns to Shopify fields, validates prices, SKUs, images, and required data, then exports a Shopify-ready CSV or sends products directly to your store.

How it works

Three steps from messy supplier file to Shopify-ready products.

Upload

Drop your CSV, XLSX, or XLS file. Portaim detects encoding, headers, and sheets automatically.

Map, validate, fix

AI maps columns to Shopify fields. 40+ rules catch errors. One-click fixes and smart suggestions resolve issues.

Export

Download a clean Shopify-formatted CSV or export directly to your store via API.

Built for Shopify merchants who import products

If you receive product data from suppliers and need to get it into Shopify, Portaim is for you.

Dropshippers

Importing catalogs from multiple suppliers with inconsistent formats, languages, and data quality.

Store owners

Adding new product lines from wholesalers without spending hours reformatting spreadsheets.

Repeat importers

Getting updated catalogs monthly from the same supplier. Save your mapping template and reuse it instantly.

Probably not for you if:

  • You import products only once or twice a year
  • Your supplier files are already in Shopify's CSV format
  • You already have an import workflow you're happy with

Without Portaim vs. with Portaim

Manual process
  • Open supplier file in Excel, figure out which columns map where
  • Manually rename headers to match Shopify's CSV template
  • Fix price formats, status values, weight units row by row
  • Upload to Shopify, get cryptic errors, go back and fix more
  • Repeat for every supplier, every month
Tedious, error-prone, and repeated for every supplier
With Portaim
  • Upload file — AI maps columns automatically, even in other languages
  • 40+ validation rules flag the issues Shopify would reject
  • One-click auto-fix for prices, formatting, status values
  • Download a Shopify-ready CSV with common import errors already caught
  • Save your mapping — next month's file from the same supplier reuses it automatically
Automated, repeatable, and gets smarter with each import
AI mapping

Skip the column-by-column cleanup

Drop a supplier file, AI maps every column to its Shopify field. Auto-matches the obvious ones, suggests the rest with a confidence score. You review and tweak — that's it.

Portaim's AI column mapping screen for Shopify product imports — supplier CSV headers automatically matched to Shopify fields, with confidence-scored AI suggestions for ambiguous columns
Portaim's validation and auto-fix screen for Shopify CSV imports — automatic normalization of booleans, currency symbols, and weight units, with remaining errors and warnings flagged inline before export
Validation

See every issue before you export

40+ rules check each cell against what Shopify enforces — duplicate SKUs, invalid prices, broken image URLs, missing required fields. Common formatting issues fix themselves automatically; the rest are flagged inline so you can resolve them before upload, not after a failed import.

Multilingual

Works in your supplier's language

When AI fills in missing titles, descriptions, or alt text, it writes them in the same language as the file. German supplier file? German product copy. French file? French. No translation step before or after.

Portaim's multilingual AI content generation — German product descriptions auto-generated for empty rows in a German supplier file, in the same language as the source file, before Shopify import
Export

Push to Shopify, or download a clean CSV

When the file's clean, push products straight to your Shopify store via API — no manual import step. Or download a Shopify-ready CSV if you'd rather upload it yourself or review it first. You're not locked into either path.
