How to add common word in a filled column ?

Hi and welcome to the forum

a quick way to do this is to add a helper column, and then, assuming your data is in A2 downwards, use this...
="S/o"&A2 (you didnt specify where you wanted it added, so move it to where you need it)

When you have copied that down, then copy/paste values over the original data, and then delete the helper column

An easy way could be this.

Add a new column. Lets's sat that column with names is column A, starting in A2.

In the new column in row 2 put this and copy down.

=A2&" "&"s/o"

Hide column A if you like.

You are welcome and thanks for the feed back.
