Assuming your "AME 013" is in cell A1, enter this formula in a helper
column:

="623"&A1

and copy the formula down for as many entries as you have in column A.

You can fix the values if you want using Paste Special.

Hope this helps.

Hello! In a cell, I have "AME 013". I want to insert "623" to the

do I go about doing this? Obviously I have a ton of them to do
otherwise I would just type it in! Thanks in advance! Jen
