You can control the display of formulas in the following ways:
Switch between displaying formulas and formula results on a worksheet This method is a toggle between two different display modes. It does not change the state of the cells.
Prevent formulas from displaying in the formula bar by protecting the cells that contain them This method changes the state of the cells – protected cells cannot be edited.
Show hidden formulas by removing the protection from cells This method changes the state of the cells – unprotected cells can be edited. Make sure this is an acceptable risk, and make a backup copy of the workbook before you proceed.
