在 Google 表格中，当您知道查找列名称和结果列名称时，如何在一行的列中找到值？

Question

I have a Sheet1 with data like this:

one	two	three	four
a	b	c	d
e	f	g	h
i	j	k	l
m	n	o	p

I have Sheet2 with data like this:

alpha	value
c
k
g
c

For each row in Sheet2 , I want to look up Sheet2 . alpha in Sheet1 . three and return the value of Sheet1 . one . I want to do this by putting an array formula in B2 .

So, the expected result is:

alpha	value
c	a
k	i
g	e
c	a

I can use the new Google Sheet formulas they just released -- except named ranges. I feel like there is some clever trick using them, but I can't come up with it.

Answer 1

BYROW() and XLOOKUP() are your friend in this case.

=BYROW(A2:INDEX(A2:A,COUNTA(A2:A)),LAMBDA(x,XLOOKUP(x,Sheet1!C2:C,Sheet1!A2:A,"Not Found")))
