Array formulas/selecting data
 

Hi, I would like to use an array formula to retrive an array of data from a
column given a certain condition, for sake of example let the columns look
like this

A B
1 1
2 2
1 3
4 4
5 5

Selecting 2 cells and using the array formula (ctrl+shift+enter)
If("A1:A5"=1;"B1:B5";"") yields the value 1 in both cells.

What do I do to get the full array, in this case 1,3 in the cells
respectively?

I want to use this as a VLOOKUP function where the lookup range doesnt have
unique elements so any other suggestions on this matter are highly
appriciated as well.

Enter the below formula and copy down as required..which should give 1,3 etc;.

=SMALL(IF($A$1:$A$5=1,$B$1:$B$5,""),ROW(A1))

Correction...Try the below array formula..and copy down .

=INDEX($B$1:$B$5,SMALL(IF($A$1:$A$5=1,ROW($B$1:$B$ 5)),ROW(A2)))

You can change the value 1 to a cell reference

=INDEX($B$1:$B$5,SMALL(IF($A$1:$A$5=<cell reference,ROW($B$1:$B$5)),ROW(A2)))
