Can I export a report to an Excel spreadsheet? 

At this time, it is not possible to export reports. You can see them in tabular form, but only in the admin panel of your store.  

Can I export my sales to an XML file?

You can download your sales in CSV format and convert them to XML using a convector of your choice. We recommend not use an online converter because that way your order data might fell into wrong hands.
