Warrain,

If you are using a simple Word document with a table then you can't enter
raw numbers and have the come out formatted in real time. You can type your
numbers as raw then select the appropriate cells and format all selected
cells using a macro. Here is an example:

Sub ConvertSelectedRawNumbersInTableToCurrencyFormat()

If Not Selection.Information(wdWithInTable) Then
MsgBox "Place cursor in a table cell or select multiple cells."
Exit Sub
End If

Dim oCl As Word.Cell
Dim oRng As Range
Dim Count As Integer
For Each oCl In Selection.Cells
Set oRng = oCl.Range
oRng.End = oRng.End - 1
With oRng
If IsNumeric(oRng) Then
.Text = FormatCurrency _
(Expression:=.Text, _
NumDigitsAfterDecimal:=2, _
IncludeLeadingDigit:=vbTrue, _
UseParensForNegativeNumbers:=vbTrue)
End If
' If InStr(oRng.Text, "$") = False Then
If IsNumeric(oRng) = False Then
Count = Count + 1
End If
End With
Next oCl
If Count = 0 Then
MsgBox "Conversion complete."
End If
Selection.Collapse wdCollapseEnd
If Count = 1 Then
MsgBox "The selected cell is empty or content is not numerical.", ,
"Notice!!"
End If
If Count 1 Then
MsgBox "" & Count & " of the selected cells are empty or content is not
numerical. Conversion complete on all selected numerical cells.", ,
"Notice!!"
End If
End Sub

I can see how to custom format the sum of a column of numbers but not
how to format the raw numbers entered into the individual cells
above. Be great if someone could put me on the right track please.
Many thanks
