Hi all,

Is there any way to limit the amount of columns in a workbook or sheet. Currently when you get to Z it then goes onto AA AB etc ideally I would like the sheet to stop at Z as I am trying to name a cell AA2 but as you can appreciate there is already a cell called AA2 so Excel takes me to that rather than letteing me name it as below
