Ok, we got it over here finally! The below works 100% of the time.

=IF(ISNUMBER(A1),CONCATENATE(LEFT(FIXED(A1,0,TRUE) ,3),IF(LEN(FIXED(A1,0,TRUE))-3=10,"E","E0"),LEN(FIXED(A1,0,TRUE))-3),A1)

Ok, we can do the macro ok.

Thanks again for all your valued help!!!!!

We transfer data from a database to Excel for multiple reasons. The ID to
our records are 6 characters such as "123A12" "456B12". When we have an ID
such as "419E07" Excel automatically changes that to 4.19E+09. A group of
us has tried EVERYTHING we know to stop this from happening. When we open
Excel, we DO NOT want Excel to convert. Any ideas?
