Good to know

Common questions

Know what’s checked before you import.

Does my CSV leave my browser?

No. Parsing, validation, and downloads happen locally in your browser. We do not upload or store your product data.

Will this change my prices or SKUs?

No. Prices, SKUs, inventory quantities, vendors, tax settings, product categories, and variant relationships are never changed by safe auto-fixes.

Are repeated product handles an error?

No. Variants and additional images can share a product handle. The validator checks product groups and flags conflicting titles or option combinations for review.

Does a score of 100 guarantee a successful import?

No. The score reflects the checks this tool can perform offline. Store settings, existing products, metafield definitions, and image availability need separate review.

Does it support older Shopify CSV templates?

Yes. Common legacy headers such as Handle, Variant SKU, and Image Src are recognized and can be normalized to the current format.
