Thanks for your feedback on this issue – while we’d like to enable this, there is currently no timetable around doing so. There is the option as a workaround the create a paginated view as a drillthrough of the visual and have a formatted version you can export to Excel, but understand this isn’t a solution everyone can take advantage of currently.
Alternative for everyone who cannot wait for this in PowerBI: SeekTable (online pivot table tool) can export pivot tables to Excel -- either as worksheet with data or as Excel PivotTable.
