Compare native Shopify product CSVs locally before import.
About VariantLedger
VariantLedger compares a current native Shopify product CSV with a proposed import in your browser. Review price changes, variant identifiers, ambiguous matches and supported file-format problems, then export CSV or JSON findings. The free preview accepts 100 data rows per file. Catalog files stay on your device; no store connection or AI API is used. It never imports or modifies a store and does not guarantee import success. A USD 29 offline edition is proposed but is not yet for sale.
