Hello there.
Why not use something simple like:
In a cell next to the top piece of data type a space and apostrophe.
Then in an empty cell on the same line use =right(a1,1) & a2
where A1 is the cell with the apostrophe and a2 is the cell with your number .
Once done rip it down as far as you want.
If needed highlight new column of data and copy- Paste special values over
the top of your formulas to hard case them in.
