This is happening because the format in Excel for the cell format was changed to Date. This could happen in case the date was copied and pasted from somewhere else, or if the cell format in Excel was changed manually.


The cell format should always be Text.

 You can avoid the change to cell format by entering the value directly in cell. If you copy it from somewhere else, paste only the value and this will not change the cell format.
