You'll need more than formatting--maybe an event macro???
Rightclick on the worksheet tab that should have this behavior. Select view
code and paste this into the code window:
Option Explicit
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Cells.Count > 1 Then Exit Sub
If Intersect(Target, Me.Range("a:a")) Is Nothing Then Exit Sub
On Error GoTo errHandler:
Application.EnableEvents = False
Target.Value = StrConv(Target.Value, vbProperCase)
errHandler:
Application.EnableEvents = True
End Sub
This entry:
I converted the typed in value to proper.
would be changed to:
I Converted The Typed In Value To Proper
If you only wanted the first letter of the first word capitalized, then change:
Target.Value = StrConv(Target.Value, vbProperCase)
to
Target.Value = ucase(left(Target.Value,1)) & lcase(mid(target.value,2))
