Creating a Plus/Minus Button

On some calculators there is a little button that can come in very handy: the plus/minus button. This button, when pressed, will switch whatever value is on the display between its positive and negative values. For instance, if the display shows the number 57, then pressing the button will change the display to -57. Pressing it again will switch the value back to 57.

If you would like a "button" that does this in Excel, you'll quickly find that there is none built into the program. You can quickly create one, however, by using a macro:

Sub PlusMinus()
    Dim cell As Range

    On Error Resume Next 'copes with cells that are not numeric
        For Each cell In Selection
            If Not cell.HasFormula Then cell.Value = -cell.Value
    Next cell
End Sub

Note that the macro simply steps through whatever range of cells you selected when the macro started. Each cell is tested to make sure it contains a numeric value. When would a cell not contain a number? The most critical time is when it contains a formula, you don't want to mess those up. Another instance is when the cell contains a date. You don't want to change those dates to minus values. Cells that contain either a formula, a date, or a label will generate an error since "cell.Value" isn't a numeric value. If the cell truly contains a number, then the result is a switch in sign for the number.

You can assign this macro to a shortcut key or add it to the Quick Access Toolbar to make it easy to use at any time.

Note:

If you would like to know how to use the macros described on this page (or on any other page on the ExcelTips sites), I've prepared a special page that includes helpful information. Click here to open that special page in a new browser tab.

The subject of this Tip is very similar to a recent Tip titled Negating a Cell Using a Macro. That Tip attracted a plethora of Comments.
See https://excelribbon.tips.net/T010127_Negating_a_Cell_Using_a_Macro.html

My Excel Toolbox includes the Negate macro to negate all numeric constants in a Selection (ignoring other cells). The Negate macro supports Undo.

Hi Allen.
Great code.
A small observation: If you apply this code to empty cells it will change it to a cell with a zero.
This small change should fix that.

Sub PlusMinus()
Dim cell As Range

On Error Resume Next 'copes with cells that are not numeric
For Each cell In Selection
If Not cell.HasFormula and cell.Value <> 0 Then cell.Value = -cell.Value
Next cell
End Sub
