I need a way to timestamp an adjacent cell whose value changes via formula. Using this as an example I need the cell adjacent to A1 on sheet 1 to timestamp the date and time when the cell value changed.
The example I have linked to above initiates a message box when the cell value changes via formula (worksheet_change events don’t appear to recognise changes to a cell value when it contains a formula whose value is changed because of a cell change elsewhere). I don’t want the message box but I do want a timestamp.
For simplicity I will post the instructions at that linked question here, any additional help with this specific question is appreciated.
In Sheet1 Cell A1, put this formula
Now In a module paste this code
Public PrevVal As Variant
Paste this in the Sheet Code area
Private Sub Worksheet_Calculate() If Range("A1").Value <> PrevVal Then MsgBox "Value Changed" PrevVal = Range("A1").Value End If End Sub
And lastly in the ThisWorkbook Code area paste this code
Private Sub Workbook_Open() PrevVal = Sheet1.Range("A1").Value End Sub
MsgBox "Value Changed" to:
Range("B1").Value = Format(Now, "dd/mm/yyyy hh:mm:ss")
or whichever timestamp format you require
