I need help using the search and replace functions. I need to find a
12 character long string of numbers within a text string. The problem
is that the location of the 12 character string is not always the same
within the whole text string and string is different in nearly every
instance. the only constants are that it is 12 characters long, where
every character ranges from 0 to 9 and the string is always preceded
and followed by a space character.

I was trying to use wildcards to search for any 14 character string
beginning and ending with ^w (whitespace) which can be done in WORD
but evidently not in excel,

Alternativley i tried to search for a 12 character string made up only
of characters 0,1,2,3, etc. but came up empty.

any help is appreciated.
