Returning multiple values in Excel - excel-formula

Question

I have this Excel file.
The layout is like this:
[Sheet1]
No | Alphabet | Fruit
1 | ABC |
2 | DEF |
3 | GHI |
[Sheet2]
Alphabet | Fruit
ABC | apple
ABC | pear
DEF | vegetable
I'd like to fill in the 'Fruit' column(s) in Sheet1.
What I currently have is this (which I put in C2 and drag down):
=INDEX(list!$A:$B,MATCH($B2,list!$A:$A,0),2)
Unfortunately, this only gives me the first match for each alphabet, like this:
[Sheet1]
No | Alphabet | Fruit
1 | ABC | apple
2 | DEF | vegetable
3 | GHI | #N/A
What I want to do is (in Sheet1) to return all matches under Fruit and replace 'vegetable' and '#N/A' to 'NIL', like this:
[Sheet1]
No | Alphabet | Fruit
1 | ABC | apple | pear
2 | DEF | NIL
3 | GHI | NIL

Answer 1

The following array formula will do somewhat what you want:
=IFERROR(INDEX(Sheet2!$B$2:$B$4,MATCH(1,(Sheet2!$B$2:$B$4<>"Vegetable")*(Sheet2!$A$2:$A$4=$A1)*(COUNTIFS($A1:A1,Sheet2!$B$2:$B$4)=0),0)),"")
It will return a null string instead of NIL
Being an array formula it needs to be confirmed with Ctrl-Shift-Enter instead of enter when Exiting edit mode. If done correctly then Excel will put {} around the formula.
The reason I went with "" instead of "NIL" is that this formula is designed to be drug/copied across and down. It would fill every cell with NIL where the formula is not a fruit.
