It would be nice to have natively some kind of copy-paste of data between excel and kendo 

more and more clients are requesting this feature but currently it is pretty difficult to implement..

being more specific the expected behavior should be:

user copying a range of cells from excel

pastes it into a grid cell 

data should spread starting from the cell where it was pasted and inserting new rows if there are not enough to contain all the content

then user should be able to copy a range of cells/rows or a single row and paste it to excel
