Saving a Workbook When a Specific Cell Is Changed

Sometimes, you may want to save a workbook when a specific cell is changed or range of cells is changed. This allows you to define the range of cells that, when changed, forces the workbook to save.

Macro Code to Saving a Workbook When a Specific Cell Is Changed

Private Sub Worksheet_Change(ByVal Target As Range)

'Step 1: Does the changed range intersect specified range?
    If Intersect(Target, Range("A5:A10")) Is Nothing Then

'Step 2: If there is no intersection, exit procedure
    Exit Sub

'Step 3: If there is an intersection, save the workbook
    Else
    ActiveWorkbook.Save

'Close out the If statement
    End If

End Sub

How This Macro Works

The secret to this code is the Intersect method. Because we don’t want to save the worksheet when any old cell changes, we use the Intersect method to determine if the target cell (the cell that changed) intersects with the range we have specified to be the trigger range (A5:A10 in this case).

The Intersect method returns one of two things: either a Range object that defines the intersec- tion between the two given ranges, or nothing. So in essence, we need to throw the target cell against the Intersect method to check for a value of Nothing. At that point, we can make the decision whether to save the workbook.

  1. In Step 1, we are simply checking to see if the target cell (the cell that has changed) is in the range specified by the Intersect method. A value of Nothing means the target cell falls outside the range specified.
  2. Step 2 forces the macro to stop and exit the procedure if there is no intersection between the target cell and the specified range.
  3. If there is an intersection, Step 3 fires the Save method of the active workbook, overwriting the previous version.
  4. In Step 4, we simply close out the If statement. Every time you instantiate an If…Then…Else check, you must close it out with a corresponding End If.

How to Use This Macro

To implement this macro, you need to copy and paste it into the Worksheet_Change event code window. Placing the macro here allows it to run each time you make any change to the sheet.

  1. Activate the Visual Basic Editor by pressing ALT+F11.
  2. In the Project window, find your project/workbook name and click the plus sign next to it in order to see all the sheets.
  3. Click in the sheet from which you want to trigger the code.
  4. Select the Change event from the Event drop-down list.Worksheet Change Event
  5. Type or paste the code in the newly created module, changing the range address to suit your needs.
