Business Importer: Orders CSV

Shopify's built-in CSV import covers products only. This app also imports past orders with line items, customers and stock levels, from a CSV or Excel export of WooCommerce, Etsy, Wix, Squarespace or any spreadsheet. Column headings are matched to Shopify fields for you, and your rows are shown under those fields before anything is created. A file in Google Drive, Dropbox or OneDrive can be re-read on a schedule. If an import was wrong, undo it: what it created is removed, existing records stay.
