Does the cell have a number?
I want a formula that will tell me if a given cell has a number in it, so it
evaluates the type of data. I looked in the help files and couldn't figure this out. Thanks, Craig |
=ISNUMBER(a1)

I tried that, but if the cell has numbers and text, it replies back with
FALSE. I would like to be able to determine if any part of the cell contents is a number, even if the string starts with, or contains letters. Thanks!

You could use a UDF Function hasNumbers(myString As String) As Boolean If myString Like "*[1234567890]*" Then hasNumbers = True Else hasNumbers = False End If End Function usage is: =hasNumbers(cellref) Gord Dibben Excel MVP On Tue, 25 Jan 2005 13:15:33 -0700, "Fletcher" wrote: I tried that, but if the cell has numbers and text, it replies back with FALSE.

Would you mind explaining why this formula works?

MID(A1, ROW(INDIRECT("1:" & LEN(A1))), 1) allows the string to be split into
individual entries CODE(..) returns the ascii code for each character - I'm looking for numbers which are in the range 48 to 57 for "0" to "9" Then subtract 52.5, which is midway between 48 and 57 48+(57-48)/2 where (57-48)/2 = 4.5 ABS turns negative numbers to positive. So this means ascii codes for numbers are from 0 to 4.5 Check to see whether any of the numbers are less than or equal to 4.5 which returns a series of TRUE/FALSE -- turns TRUE, FALSE to 1, 0 SUMPRODUCT adds the entries of an array. 0 means the count of characters which were identified as numbers -- Rob van Gelder - http://www.vangelder.co.nz/excel "tjtjjtjt" wrote in message ...

Thank you. It's quite clever.
