Compatibility

Works with Shopify product CSV exports, with current and older column names.
UTF-8 with optional BOM; comma, semicolon or tab input with explicit delimiter confirmation.
USD, EUR, GBP, CAD, AUD, CHF (2 decimals); JPY (0); KWD (3). No FX or thousands separators.
Runs online in current Chrome, Edge, Firefox and Safari. Nothing to install; files stay in your browser tab.

Limits

Shopify: 15 MB and 50,000 variant rows. Supplier: 25 MB and 100,000 rows. 1 MB per cell and 256 columns.
Prices for existing variants only. No stock, titles, images, options, direct store writes or product creation/deletion.
Unit-priced products are blocked: Shopify price-only imports can disable unit-price display. Keep the full fresh export; do not remove unit-price columns to bypass this guard.
Linked metafield options, conflicting dialects or unsafe variant identity are blocked. Above 15 MB output is blocked; select fewer complete products.

Good to know

Keep your untouched full Shopify export as a backup and import one product first. Native CSV overwrite can have side effects; rollback restores the candidate prices and is best-effort.
CSV processing and downloads run locally in the browser. No account or store credentials required, and no files are uploaded.
One-time $19 USD purchase: permanent online access to version 1 (1.x) of the full tool. Sign in with an emailed single-use link; no password. License, support and refund terms are shown and accepted at checkout.
