The new experience reports supposedly export to excel and .csv BUT when doing so for excel the values are stored as text and for .csv come with a preceding accent character rendering both reports pretty useless without time consuming formatting. 
I hoped they would improve on the poor existing report exports to excel that come with unnecessary and frustrating formatting (like the old sage ones).
when asking support they say "It's not technically an issue but more of a working as designed kind of feature" 
Does anyone know if that is correct and they are supposed to export values as text?
