conditional flashing cells

Yes, you can make a cell flash only when a condition is met, like when one value exceeds another:

1. Create a Custom Cell Style
•    Go to the Home tab → Cell Styles → New Cell Style
•    Name it something like "FlashingText"
•    Set formatting (e.g. bold red font, colored background)

2. Open the VBA Editor
•    Press Alt + F11 to open the editor
•    Insert a new module: Insert → Module

3. Paste This VBA Code

Public NextTime As Double
Public Const FlashRng As String = "Sheet1!A1" ' Change to your target cell

Sub FlashCell()
    If Range(FlashRng).Value > Range("B1").Value Then ' Your condition
        If Range(FlashRng).Style = "FlashingText" Then
            Range(FlashRng).Style = "Normal"
        Else
            Range(FlashRng).Style = "FlashingText"
        End If
        NextTime = Now + TimeSerial(0, 0, 1)
        Application.OnTime NextTime, "FlashCell", , True
    End If
End Sub

Sub StopFlash()
    On Error Resume Next
    Application.OnTime NextTime, "FlashCell", , False
    Range(FlashRng).Style = "Normal"
End Sub

4. Run the Macro
•    Go to the Developer tab → Macros → Run FlashCell
•    Or use Workbook_Open to trigger it automatically when the file opens
