Auto-fill the date in a cell, when the user enters

问题:

I have a spread sheet, where people can enter project updates and then the date of the update. What is happening is that people are forgetting to date their notes. Is there a way to have the date cell autopoplute the current/date of entry?

I am assuming an if function would do it?

This event macro will place the date in column B if a value is entered in column A. The macro should be installed in the worksheet code area:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim A As Range, B As Range, Inte As Range, r As Range
    Set A = Range("A:A")
    Set Inte = Intersect(A, Target)
    If Inte Is Nothing Then Exit Sub
    Application.EnableEvents = False
        For Each r In Inte
            r.Offset(0, 1).Value = Date
        Next r
    Application.EnableEvents = True
End Sub

Because it is worksheet code, it is very easy to install and automatic to use:

1. right-click the tab name near the bottom of the Excel window
2. select View Code - this brings up a VBE window
3. paste the stuff in and close the VBE window

If you have any concerns, first try it on a trial worksheet.

If you save the workbook, the macro will be saved with it. If you are using a version of Excel later then 2003, you must save the file as .xlsm rather than .xlsx

To remove the macro:

1. bring up the VBE windows as above
2. clear the code out
3. close the VBE window

Macros must be enabled for this to work!

Change the code to use different columns.

EDIT#1:

This version will not overwrite material already present in column B:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim A As Range, B As Range, Inte As Range, r As Range
    Set A = Range("A:A")
    Set Inte = Intersect(A, Target)
    If Inte Is Nothing Then Exit Sub
    Application.EnableEvents = False
        For Each r In Inte
            If r.Offset(0, 1).Value = "" Then
               r.Offset(0, 1).Value = Date
            End If
        Next r
    Application.EnableEvents = True
End Sub

ZAT's answer worked for me... AFTER I changed the ";"s to ","s.

=IF(AND(D52<>"",D52<>0),NOW(),"")

I used "NOW" instead of "TODAY" to give me the time of day.

Try this formula in the desired cell (e.g C13) to fill the current date when corresponding input cell (e.g D13) is not empty and not filled with 0 :

=IF(AND(D13<>"";D13<>0);TODAY();"")

And then you can copy this formula to the subsequent cells to fill in the formulas for that column (e.g col C)

Enter Date & Time in column A & B with the data entry in column D

Private Sub Worksheet_Change(ByVal Target As Range)
Dim A As Range, B As Range, Inte As Range, r As Range
Set A = Range("D:D")
Set Inte = Intersect(A, Target)
If Inte Is Nothing Then Exit Sub
Application.EnableEvents = False
    For Each r In Inte
        If r.Value > 0 Then
           r.Offset(0, -3).Value = Date
           r.Offset(0, -3).NumberFormat = "dd-mm-yyyy"
           r.Offset(0, -2).Value = Time
           r.Offset(0, -2).NumberFormat = "hh:mm:ss AM/PM"
        Else
           r.Offset(0, -3).Value = ""
           r.Offset(0, -2).Value = ""
        End If
    Next r
Application.EnableEvents = True
End Sub
