Please Note: This article is written for users of the following Microsoft Excel versions: 97, 2000, 2002, and 2003. If you are using a later version (Excel 2007 or later), this tip may not work for you. For a version of this tip written specifically for later versions of Excel, click here: Flashing Cells.
Many people use the conditional formatting features of Excel to draw attention to specific values or areas of their worksheets. For instance, a cell might be formatted so that its contents are displayed in red or in boldface if above or below a certain threshold.
What is missing, however, is a way to make the contents of a cell flash, or blink on and off. For such a feat, you are left to your own devices and the miracle of macros. By utilizing these tools, you can make cells blink by first designing a special style for the blinking cells, and then running a simple macro.
To create the special style, follow these steps:
- Select the cell that you want to flash on and off.
- Choose Style from the Format menu. Excel displays the Style dialog box. (See Figure 1.)
Figure 1. The Style dialog box.
- In the Style Name box, enter a new style name. (For this example, use the style name Flashing.)
- Using the controls in the dialog box, modify any attributes for the style, as you desire.
- Click on OK.
You can now apply the style to any other cells you desire in your workbook. Now create the macros (there are two of them), as follows:
Dim NextTime As Date
NextTime = Now + TimeValue("00:00:01")
If .ColorIndex = xlAutomatic Then .ColorIndex = 3
.ColorIndex = 5 - .ColorIndex
Application.OnTime NextTime, "StartFlash"
Application.OnTime NextTime, "StartFlash", schedule:=False
ActiveWorkbook.Styles("Flashing").Font.ColorIndex = xlAutomatic
To start the items flashing, simply run StartFlash. The cells formatted with the Flashing style will alternate between red and white text approximately once a second. When you want to turn the flashing off, simply run the StopFlash macro.
There is one important thing to note about this macro: the variable NextTime is declared outside of the actual procedure in which it is used. This is done so that NextTime maintains its value from one invocation of StartFlash to the next.

I made a template about flashing cell.
Barry 31 Jul 2015, 05:54
I have a spreadsheet that does exactly this.
I use a very simple macro that toggles the value of a "Name" once per second. Then I use conditional formatting to either highlight the target cell or not dependent on the value in the Name.
NB a Name doesn't have to refer to a Named range which it is most commonly used for but can hold variables, or even formulas.
In a code "Module":
Public HighlightTime As Date
If ThisWorkbook.Names("Flash") = "=1" Then
ThisWorkbook.Names("Flash").Value = "=0"
ThisWorkbook.Names("Flash").Value = "=1"
HighlightTime = Now + TimeValue("00:00:01") 'SetTime for +1 secs
Application.OnTime HighlightTime, "RefreshHighLight"
and on the "ThisWorkbook" codepage:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
Application.OnTime HighlightTime, "RefreshHighLight", , False
Private Sub Workbook_Open()
Then in any cell you want to flash use the conditional formatting forumla: "=Flash=1" and whatever formatting you desire.
NOTE: the placement of the macro on the specified codepages/modules it important.
and the use of these macros clears the "Undo" stack.

Is it possible to highlight a cell say in yellow and just have the highlighted colour flash on and off. The contents i.e. text or numbers of the cell should stay the same.

Very handy! I use it inside a stopwatch macro for tracking billable hours while I work.
Instead of changing font colour, though, it may be easier just to toggle bold:
.Bold = Not .Bold

Just a tip for others, DON'T use black as the base color. The macro is subtacting to get the alternate color. And BLACK is 1.
Styles format menu is accessed from HOME ribbon, Styles box, Cell Styles drop down.

This page is for users of older versions of Excel, as noted at both the beginning and end of the tip. Also in those places (beginning and end) is a link to a tip for later versions of Excel, including yours.

Is it possible to make the cell flash if the date is reaching close to 30 days. I want to be notified that a client has not called within the 30 days period so that when it starts to flash I can call them.
Barry Fitzpatrick 01 Jun 2013, 06:21
It is some times easier for Users simply to have the macro toggle a cell value between TRUE and FALSE and use conditional formatting to flash whatever formatting the user desires without the need to delve into the macro itself and the to have knowledge of properties of the of cells and restrictions on the value they can be set to.
