jjakel, you can with some code, put in worksheet code, right click on the
worksheet tab a view code, paste this in, will put an X in column A when you
click in it, will also remove it if you click it again

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
If Target.Count 1 Then Exit Sub
If Target.Column = 1 Then
If Len(Trim(Target.Value)) = 0 Then
Target.Value = "X"
Else
Target.ClearContents
End If
End If
End Sub

You could also make it put in a check mark like this

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range)
If Target.Count 1 Then Exit Sub
If Target.Column = 1 Then
If Len(Trim(Target.Value)) = 0 Then
Target.Value = Chr(252)
Target.Font.Name = "Wingdings"
Target.Font.Size = 10
Else
Target.ClearContents
End If
End If
End Sub

In Excel, I want to have a spreadsheet where users can check-mark cells,
just
by clicking that cell...not actually having to type an X in it. Is this
possible and if so, how?
