finding the minum rows name

Do you mean find the column name ??

I would put in A2, and fill across to column M (or however many you need):-

=if(A1=min($A$1:$M$1),col(),"")

In row 2, a number will a appear in 1 cell only, that number is the numerical representation of the column 'number', ie A=1 , B=2 etc.

like this in here i make this for a 25 rows

Again, I'm guessing you mean 25 columns, A to Y, not 25 rows ??

OK, seeing you have so many, it cant be done with a nested IF formula, that only allows 7, unless you had 4 hidden columns, each with a messy formula.

No, I would guess that you'd have to write a macro to do it.

can you show me the solution
