How to Hide Formulas in an Excel Spreadsheet

1. Locate the cells with the formulas you want to hide.
2. Select those cells by clicking and dragging with your mouse.
3. Right-click on your selection, and select 'Format cells' from the resulting menu. In the window that appears, select the tab titled 'Protection' and check the check box labeled 'Hidden.' Click 'OK' to finish.
4. Finally, select the 'Review' tab in Excel's main window, and select the 'Protect Sheet' option. This final step will ultimately hide your formulas. If you want to view them again, disable the protection on the sheet. You can also password-protect the sheet if need be.
