Separating strings from numbers with Excel VBA - regex

Question

I need to
a) separate strings from numbers for a selection of cells
and
b) place the separated strings and numbers into different columns.
For example , Excel sheet is as follows:
A1 B1
100CASH etc.etc.
The result should be:
A1 B1 C1
100 CASH etc.etc.
Utilization of regular expressions will be useful, as there may be different cell formats,such as 100-CASH, 100/CASH, 100%CASH. Once the procedure is set up it won't be hard to use regular expressions for different variations.
I came across a UDF for extracting numbers from a cell. This can easily be modified to extract string or other types of data from cells simply changing the regular expression.
But what I need is not just a UDF but a sub procedure to split cells using regular expressions and place the separated data into separate columns.
I've also found a similar question in SU, however it isn't VBA.

See if this will work for you:
UPDATED 11/30:
Sub test()
Dim RegEx As Object
Dim strTest As String
Dim ThisCell As Range
Dim Matches As Object
Dim strNumber As String
Dim strText As String
Dim i As Integer
Dim CurrCol As Integer
Set RegEx = CreateObject("VBScript.RegExp")
' may need to be tweaked
RegEx.Pattern = "-?\d+"
' Get the current column
CurrCol = ActiveCell.Column
Dim lngLastRow As Long
lngLastRow = Cells(1, CurrCol).End(xlDown).Row
' add a new column & shift column 2 to the right
Columns(CurrCol + 1).Insert Shift:=xlToRight
For i = 1 To lngLastRow ' change to number of rows to search
Set ThisCell = ActiveSheet.Cells(i, CurrCol)
strTest = ThisCell.Value
If RegEx.test(strTest) Then
Set Matches = RegEx.Execute(strTest)
strNumber = CStr(Matches(0))
strText = Mid(strTest, Len(strNumber) + 1)
' replace original cell with number only portion
ThisCell.Value = strNumber
' replace cell to the right with string portion
ThisCell.Offset(0, 1).Value = strText
End If
Next
Set RegEx = Nothing
End Sub

How about:
Sub UpdateCells()
Dim rng As Range
Dim c As Range
Dim l As Long
Dim s As String, a As String, b As String
''Working with sheet1 and column C
With Sheet1
l = .Range("C" & .Rows.Count).End(xlUp).Row
Set rng = .Range("C1:C" & l)
End With
''Working with selected range from above
For Each c In rng.Cells
If c <> vbNullString Then
s = FirstNonNumeric(c.Value)
''Split the string into numeric and non-numeric, based
''on the position of first non-numeric, obtained above.
a = Mid(c.Value, 1, InStr(c.Value, s) - 1)
b = Mid(c.Value, InStr(c.Value, s))
''Put the two values on the sheet in positions one and two
''columns further along than the test column. The offset
''can be any suitable value.
c.Offset(0, 1) = a
c.Offset(0, 2) = b
End If
Next
End Sub
Function FirstNonNumeric(txt As String) As String
With CreateObject("VBScript.RegExp")
.Pattern = "[^0-9]"
FirstNonNumeric = .Execute(txt)(0)
End With
End Function
