inserting a character (comma, paragraph return) into text string
I have a text string that I want to add a character like a comma or paragraph return every 4 characters.
For example I have a string like GE09GE08GE07 and I need to separate this into GE09,GE08,GE07
Is there a calculation function that can do this? I've tried left with repeats but it just gives me the same 4 characters over and over, not the next four.
