To reproduce the issue, open a new excel file, put value 1 in A1, 2 in A2 & 3 in A3.
Select the first 3 cells from excel & press Ctrl+C.
Now go the sample url, select the first three cells in the Price column and press Ctrl+v.
I am able to see that while the contents are being updated for the first three cells, however the fourth cell(within the price column), gets updated by itself to value $0.
Did anyone has any idea how to prevent the fourth cell from being updated, i.e. when the data is copied from an excel file and copied into the grid?
