Thanks for your answer. But my question is, if those multiple cells have data
contents already, and I want to add the same words after the data in each of
the multiple cells, what should I do?
If all of these are going to have the same data at all times, just have one
cell be the one you edit, i.e.: A1, and have all other cells have the formula
=$A$1, and then any change you make in A1 will be carried through all other
cells.
