Hello, I am wanting to spill an xlookup of a maximum number but am hitting a #VALUE error. The basic format is:

weekcatratintended resultbasic intent
23416cat=xlookup(max(b2:c7),$b$2:$c$7,$b$1:$c$1))
34824cat
43715cat
52540rat
65445cat
73839rat

I get that xlookup wont work in this instance so would like to use BYROW but I cannot seem to get it working. I figured something like:

=BYROW(b2:c7,LAMBDA(v,a,r,XLOOKUP(v,a,r)(max(b2:c7),b2:c7,b1:c1)) would work but no dice. Since there is a substantial variation in the number of possible rows, I do want a spilling result.

And yes I get that I should be using the downloadable mini sheet thing but that would require me to have admin rights to install on my laptop.
 

Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.
If I understand correctly, this is all you need:

Book1
ABCD
1WeekCatRatIntended Result
223416Cat
334824Cat
443715Cat
552540Rat
665445Cat
773839Rat
8
Sheet8
Cell Formulas
RangeFormula
D2:D7D2=IF(B2:B7>C2:C7,B1,C1)
Dynamic array formulas.

your right, but i have a bunch more columns to deal with, I needed to truncate for simplicity. There should be something like 26 columns.

Like this perhaps:

ABCDEFG
1catratdogslugResult
2341621cat
348245099slug
43715202cat
525404533dog
654656020rat
740393040cat
ColorCount
Cell Formulas
RangeFormula
G2:G7G2=LET(d,B2:E7,hdr,B1:E1,INDEX(hdr,BYROW(d=BYROW(d,LAMBDA(r,MAX(r))),LAMBDA(r,MATCH(TRUE,r,)))))
Dynamic array formulas.

Note that this will display only one result per row, even if there are duplicates.

This is exactly right. Thanks so very much.

Any ideas on how to do it for spilled results across and down... Eg I'm using SMALL function to find the 3 smallest values for each person:

Using your answer above only seems to be suitable for one column spill:

Thanks for responding - I'll have a play around with this... the results aren't quite correct.

@Fluff with all due respect, I don't believe this is the same, I did not post the initial question on this thread... can you please re-instate the question that I just posted as it is most definitely not a duplicate post, as this post is not mine. I believe I will get the answer I'm looking for with my own question being posted.

It is a duplicate of post#6 in this thread & the other thread will remain locked.
Also you have had an answer here, but have given no information of what is wrong.
