You might have noticed that Excel doesn't appear to offer "Boolean" as cell type. When you try to format a cell, Excel will suggest formatting its contents as a currency, a date or time, a percentage but not a boolean value. Nonetheless, Excel does process boolean values and it regularly produces them as the output from formulas. To create a cell whose boolean value you change, create a checkbox. When checked, this box will have the value of "True." When unchecked, it will have the value of "False."
