If you want to cancel one or two orders, you can use the Manage Orders feature.
However, when you want to cancel multiple orders at the same time, you can use the Order Cancellation File.
You download the Order Cancellation File template (a Microsoft Excel file) from the Order Cancellation Template page, edit the spreadsheet, save it as a tab-delimited text file, and then upload it on the Order Cancellation page.
Please note: This template contains validation macros that will help you complete the template correctly. The validations may be turned on or off at your discretion, but we urge you to keep them on until you learn how to use the template.
