Assign text to cell

I need to assign different text  for already labeled cell. purpose of this is, if I copy that already labeled cell and paste in windows notepad it should paste that assign text not label. for example there is cell displaying number "1"  and  I need to assign "abhk;f@}{ / " text for that. after that in excel it should displaying 1 and if copy that cell and paste in windows word notepad it should paste "abhk;f@}{ / "

Not number 1.

Thank you and highly appreciate your help
