For making cells blink blink to attract users’ attention, here is a VBA code.

1. Enable the sheet you want to flash cells, and press Alt + F11 keys to open Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and then paste below VBA code to the Module script. See screenshot:

VBA: Make cell flash red

Private Sub Flash_Cells()
    Dim xColor As Integer
    Dim xCount As Integer
    Dim xSpeed As Double
    Dim xStart As Double
    Dim xDelay As Double
    Dim xRg As Range
    Dim xTxt As String
    Dim xCell As Range
    On Error Resume Next
    If ActiveWindow.RangeSelection.Count > 1 Then
      xTxt = ActiveWindow.RangeSelection.AddressLocal
      xTxt = ActiveSheet.UsedRange.AddressLocal
    End If
    Set xRg = Application.InputBox("Select cells", "Kutools for Excel", xTxt, , , , , 8)
    If xRg Is Nothing Then Exit Sub
    For Each xCell In xRg
        If xCell.Value > 4 Then
            xColor = 3
            xSpeed = 0.6
            Do Until xCount = 20
                xStart = Timer
                xDelay = xStart + xSpeed
                Do Until Timer > xDelay
                    xRg.Interior.ColorIndex = xColor
                xStart = Timer
                xDelay = xStart + xSpeed
                Do Until Timer > xDelay
                    xRg.Interior.ColorIndex = xlNone
                xCount = xCount + 1
        End If
End Sub

doc flash cell 1

3. Press F5 key, and a Kutools for Excel dialog pops out for selecting cells you want to make flash, see screenshot:
doc flash cell 2

4. Click OK. Now the selected cell has been flash with red background.


(1) In the VBA code, you can change the background color (xColor = 3), blink speed (xSpeed = 0.6) and blink times (Do Until xCount = 20) as you want.

(2) This VBA code won’t add flash background to blank selection.

(3) This flash background will be removed automatically after the blank times finish.
