There is not currently a way to export a canned Query directly into an Excel file. If you want to export data from a canned Query, you'll need to create a similar custom Query via Tool #100 CU*BASE Report Builder (Query). Once you have the Query built, then you can export the resulting database file. (See the related link below for instructions on downloading files.)

Keep in mind that download authority is still required in order to export any data from the QUERYxx library.
