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

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)

f	g	h	I	j	k	l	m	n	o	p	q	r	s	t	u	v	w	x	y	z	aa	ab	ac	ad	ae	af	ag	ah	ai	aj	AK
	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30	MAX
ab cdef ghi j k lmn			3					8				12		14		16															14				row 5
										cell I4 contains the formula		IF(MID($F5,I4,1)=" ",I4,"")
										cell AK5 contains the formula		LARGE(G5:AJ5,2)
I did not know about the substitute formula and started to attack it from first principles - so I post this ti give you all a laugh										thus you have located the second space in from the right

<colgroup><col><col span="34"><col></colgroup><tbody>

Hey, nice! It worked through.

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