Extract only numbers from an alphanumeric field in Excel?

Guest

I am trying to extract only the numbers from an alphanumeric field. The
numbers are not consistently in the same spot. Example: abc123, 123abc or
a123bc... I want a returned value of "123".

Thank you

Hi Brian,

You could use this UDF (User defined Function):

' =============================================================================

Function StripTxt(a As String) As String

' Niek Otten, March 22 2006

' Strips all non-numeric characters from a string, but leaves any decimal separator

' Returns a string, not a number!

' If you need a number, use =Value(StripTxt(...))



Dim i As Long

Dim b As String

For i = 1 To Len(a)

b = Mid$(a, i, 1)

If ((Asc(b) > 47 And Asc(b) < 58) Or b = Application.DecimalSeparator) Then StripTxt = StripTxt + b

Next i

End Function

' =============================================================================



If you don't know (yet) how to implement a UDF:

If you find a VBA function on the Internet or somebody mails you one, and you don't know how to implement it, follow these steps:



Select all the text of the function. CTRL+C (that is, press and hold down the CTRL key, press C, release both). This a shortcut
for Copy.

Go to Excel. Press ALT+F11 (same method: press and hold the ALT key, press the F11 key and release both). You are now in the
Visual Basic Editor (VBE).

From the menu bar, choose Insert>Module. There should now be a blank module sheet in front of you. Click in it and then press
CTRL+V (same method.). This a shortcut for Paste. You should now see the text of the function in the Module.

Press ALT+F11 again to return to your Excel worksheet.

You should now be able to use the function as if it were a built-in function of Excel, like =SUM(..)

Download and install Longre's free morefunc.xll add-in from
http://xcell05.free.fr/

Then use the Regular Expression formula:

=REGEX.SUBSTITUTE(A1,"\D")

The expression "\D" matches anything in the string that is not a digit [0-9].
The substitute function substitutes the non-digits with a null, leaving only
digits.
