Is it possible to export Tempo report data?

You can export data to CSV or Excel via process, not via button on Tempo. There are several plug-ins available for download here in Appian Forum under the "Shared Components" record (forum.appian.com/.../all) that will allow you to do this via process. You could easily offer this possibility as a related action on your records or as an action under Actions.

Hi hansd, you could use the fn!runprocess() on click of the button in the reports/ records and this will do the required work. But opt for this only when you don't have the concern of cloud compatibility.
