How to replace just a single character from many of the same one within a text?

[dvpe]

Hi folks, I have to deal with a text database into Excel but ended up finding irregular format that need to be fixed.
As it can be seen within the text right below, there are space delimiters in between the words. I want to replace always the 2nd space from right to left with a semicolon.

20/10/2012 CENTAURO CE 39 (06/10) 57.97 0.00
20/10/2012 CENTAURO CEFT 534 (09/10) 1,235.34 0.56
20/10/2012 CENTAURO (06/10) 5,345,200.00 45.00 1.01
20/10/2012 TFRE (06/10) 1.00 0.00

Assuming text is in cell A2, formula is:
=SUBSTITUTE(A2," ",";",(LEN(A2)-LEN(SUBSTITUTE(A2," ",""))-1))

Hey,

Provided the text is in A1 then this is the formula you need. It will replace 2nd space from right to left with a semicolon.

=SUBSTITUTE(A1," ","; ",2)

Hey, nice! It worked through.

Hey,

Provided the text is in A1 then this is the formula you need. It will replace 2nd space from right to left with a semicolon.

=SUBSTITUTE(A1," ","; ",2)

It wasn't the path I meant but I got the logical idea. Nice. Thanks a lot.
