Now let's instrumentality a look astatine this function's syntax:

XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])

The archetypal 3 arguments are required:

  • lookup_value: The hunt term.
  • lookup_array: The hunt scope (or the root data).
  • return_array: The instrumentality scope (or the results).
  • if_not_found: Text returned erstwhile a valid lucifer isn't found. If omitted, the relation returns #N/A.
  • match_mode: Specifies the lucifer type. See Table A for the due values and explanations.
  • search_mode: Specifies the hunt mode. See Table B for the due values and explanations.

Table A

ValueExplanation
0Find an nonstop match; instrumentality #N/A if nary found. This is the argument's default value.
-1Find an nonstop match; instrumentality the adjacent smaller point if nary lucifer is found.
1Find an nonstop match; instrumentality the adjacent larger point if nary lucifer is found.
2Allows a wildcard match: *, ?, and ~.

Table B

ValueExplanation

That's a batch of information, but astir of it is akin to the older lookup functions. Now, let's determination connected to a fewer examples.

A speedy examination of XLOOKUP() and VLOOKUP()

XLOOKUP() tin beryllium utilized to instrumentality a azygous value, likewise to VLOOKUP(), but it uses antithetic arguments. Let's comparison the 2 functions utilizing the information acceptable successful Figure A. Specifically, we'll instrumentality the worker ID and the day utilizing the unit worth arsenic the hunt word (K1).

Figure A

  We'll usage lookup functions to instrumentality values based connected a hunt term.

First, let's reappraisal the ID functions:

K3: =VLOOKUP($K$1,Table1[[Personnel]:[ID]],2)

K4: =XLOOKUP($K$1,Table1[Personnel],Table1[ID])

Both functions usage the worth successful K1, Luke, arsenic the hunt term. The astir important happening to notation is that the VLOOKUP() relation successful K3 returns the incorrect value, whereas the XLOOKUP() relation successful K4 returns the close value. VLOOKUP() requires a sorted information set, but XLOOKUP() doesn't. XLOOKUP() returns the archetypal worth that matches—the default settings.

The functions successful L3 and L4 effort to instrumentality the day based connected the lookup value, Luke, utilizing the functions

L3: =VLOOKUP($K$1,Table1[[Personnel]:[ID]],-1)

L4: =XLOOKUP($K$1,Table1[Personnel],Table1[Date])

You astir apt expected the mistake worth successful L3 due to the fact that VLOOKUP() doesn't enactment a hunt to the near of the lookup value; the relation simply doesn't recognize the argument, -1. XLOOKUP() does, and alternatively of utilizing a antagonistic value, you notation the existent file and again, the relation doesn't caput that the information acceptable isn't sorted. In this elemental example, sorting the information wouldn't matter, but sometimes you person to enactment with the information acceptable order, truthful this caller behaviour is simply a large upgrade.

Stay tuned

At this point, you tin commencement utilizing XLOOKUP() alternatively of the older lookup functions, if you like. You person capable accusation to get started. Don't interest astir replacing the older lookup functions; it's doubtful that Microsoft volition deprecate them successful the adjacent future. 

In my adjacent article, we'll usage precocious features to usage aggregate criteria with XLOOKUP(). We'll besides larn however to instrumentality aggregate columns with 1 XLOOKUP() function.
