Mixed Case data in a cell, need to break apart

[dsforbes]

The contents of the cell are alpha numeric
some begin with 2-5 characters of alpha and 4-6 numeric
for example

ab123456
ac1234
con123456
selb23455

How to I break the contents apart to see the alpha in one column and the numeric in another
Thanks

If your data starts in A1, then in B1:

=LEFT(A1,MIN(FIND(0,SUBSTITUTE(A1,{1,2,3,4,5,6,7,8,9},0)&0))-1)

and in C1:

=SUBSTITUTE(A1,B1,"")

both copied down

Holy crap - it worked. Awesome.
Array formula....didn't think of that.
THANK YOU!!!
