How do I extract numbers from many columns in excel on to one cel.

[DFALUSA]

I have a worksheet with 9 columns, each column contains 1 number, on column
10 I want to see the 9 digits as one single number

As Text
=A1&B1&C1&D1&E1&F1&G1&H1&I1

As Number
=--(A1&B1&C1&D1&E1&F1&G1&H1&I1)

 

[CLR]

=CONCATENATE(A1,B1,C1,D1,E1,F1,G1,H1,I1)
OR
=CONCATENATE(A1,B1,C1,D1,E1,F1,G1,H1,I1)*1

Vaya con Dios,
