Hi all:

If you look at the two example numbers in the initial posting you will find
that they are different. The first will not be treated as a number under any
circumstances. I could not get any of the above tricks to work. I did
follow some of the links Nick Otten provided (thank you) and now better
understand what happened. I ran Len(A1) and the length was 10, as expected.
ISNUMBER told me that it was not a number and even after removing the first
character, it said it was not a number,but I could treat it as a number
(except formating). I next used CODE(A1) and found out that the first
character was an ASCII 160, non-breaking space. Since I will be passing this
sheet on to others, I elected to not use macros and stuck with the simple
following procedure.
I put the following number in cell A1.
Number as it was delivered to me. Any attempt to use it as a number resultes
in a #VALUE!
479811882

If I insert it into a formula (B1) like this:
Right(A1,9)
It leaves me with the number in B1:
479811882

but I am unable to format it as a number, i.e.:479,811,882.00, but I can now
use it as a number.
If I put the formula B1*1 in cell C1, the result is now a true number and
can be formated as such.
479811882


A1 B1 C1
Number Right(A1,9) B1*1

Thanks all, for your responses. I am finding this site to be a great
resource for information.
