问题
Row 1 : YORK / LEEDS / WINDSOR / CHESHIRE
Row 2 : 10 / 8 / 6 / 9
So I want to find the closest match to York in the other data across each row, and bring back the title of the closest match.
So the answer i want to bring back for row 2 (York = 10) is "CHESHIRE" as 9 is the closest to 10.
Thank you!

If your data is in A1:D2 try this "array formula"
=INDEX(B$1:D$1,MATCH(MIN(ABS(A2-B2:D2)),ABS(A2-B2:D2),0))
confirmed with CTRL+SHIFT+ENTER
If 2 or more values are equally close then the match will be with the first one from the left.....

There are reasons for avoiding array formulas, see e.g.:
A Microsoft page (look for "Disadvantages of using array formulas").
This.
If you care about this, and prefer not to use array formulas, the following works.
=INDEX(B$1:D$1,MATCH(MIN(INDEX(ABS($B2:$D2-$A2),0)),INDEX(ABS($B2:$D2-$A2),0),0))
