A 68-second walkthrough of Tikkivo Catalog Sync, a Shopify app I built: connect a supplier CSV, Excel, JSON file, published Google Sheet or JSON API, map the fields, review the proposed price and stock changes, then apply them. New products are created as drafts.
Limits: no XML or FTP in this release.
