To delete product variants in bulk in your Shopify store first ensure that you have a Products - Complete (with Variants) worksheet in your workbook. Select the rows for the variants you’d like to delete, just like you would in Excel - by clicking on the row header and dragging the mouse to cover additional row headers. Then right-click on one of the selected row headers (the row header shows the row number). In the menu that opens select the Delete object in Shopify menu option.
You’ll now see a dialog show up, confirming that you want to permanently delete the selected variant(s) in your store. Once you confirm, Mixtable will notify Shopify, asking it to delete the variants. Once the deletion is done, the variants’ data will be removed from your worksheet.
