Use one cell for entering values, then record of entry appears in adjacent column

I want this:

Each time I enter a new value in cell A1, a record of all values I've entered appears in the column of cells C1:C#...

What formula set up do I use to achieve this?

Solution 1:

Place the following event macro in the worksheet code area:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim N As Long, A1 As Range
    Set A1 = Range("A1")
    If Intersect(Target, A1) Is Nothing Then Exit Sub
    N = Cells(Rows.Count, "C").End(xlUp).Row + 1
    Application.EnableEvents = False
        Cells(N, "C").Value = A1.Value
    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!
