The supplier-to-Shopify gap

Suppliers deliver product data in spreadsheets with custom headers, mixed currencies, and missing fields. Shopify expects a specific CSV format. ProductCSVFixer bridges that gap by mapping supplier columns to Shopify fields, validating the data, blocking bad rows, and producing a Shopify-compatible export.

Works with any supplier file
Accepts CSVs from wholesalers, dropshippers, manufacturers, or marketplaces — no template required.
Smart column mapping
Auto-suggests mappings from supplier headers to Shopify fields. Review and edit before confirming.
Blocked rows explained
Rows with critical errors are excluded from export. You get a report showing exactly what to fix.
Field validation
Checks for missing titles, SKUs, prices, handles, and image URLs so nothing breaks in Shopify.

Download a Shopify-ready CSV with mapped fields and blocked rows removed. Ready for direct upload.
Browser-based processing

What we check before export

Required fields
Title, handle, price, and SKU are verified. Missing values are flagged as errors.
Data quality
Invalid prices, broken image URLs, duplicate SKUs, and malformed handles are caught early.
Row health
Clean rows pass through. Blocked rows are excluded so your Shopify import succeeds.
