XLOOKUP

Supported, behaves as documented

Category: Lookup and reference · Last tested 2026-08-06

Real, executed compatibility results for the XLOOKUP function across Microsoft Excel, Google Sheets, and LibreOffice Calc — verified by actually running it. Syntax and links to each vendor’s official documentation are below.

✓ Supported in LibreOffice since 24.8.7.2. We ran XLOOKUP under every LibreOffice release we test (24.2.0.3, 24.8.7.2, 25.2.0.3, 25.8.7.3): it returned #NAME? (unrecognized) in 24.2.0.3 and first works in 24.8.7.2. If you need XLOOKUP in LibreOffice Calc, use 24.8.7.2 or newer.

LibreOffice version history

We executed the same test cases under each LibreOffice release to show exactly when XLOOKUP’s support changed — not documentation claims, real results.

LibreOffice version	Verdict	Tested
24.2.0.3	Unsupported (not recognized)	2026-07-19
24.8.7.2	Supported, behaves as documented	2026-07-19

Why isn't XLOOKUP working in LibreOffice?

If XLOOKUP returns a #NAME? error in LibreOffice Calc, you are almost certainly running a release older than 24.8.7.2 — that is exactly what our executed tests show: #NAME? in 24.2.0.3, working from 24.8.7.2 onward. Check your version under Help → About LibreOffice and upgrade to 24.8.7.2 or newer; no setting or extension enables it in older releases. (Other causes of this error: see the error values guide.)

Executed test cases

LibreOffice Calc 25.8.7.3 (tested 2026-08-06)

Formula	Description	Result	Expected	Verdict
=XLOOKUP("b",A1:A3,B1:B3)	Basic exact-match lookup returns the corresponding value	2	2	Matched
=XLOOKUP("z",A1:A3,B1:B3)	No if_not_found arg and no match -> #N/A	#N/A	#N/A	Matched
=XLOOKUP("z",A1:A3,B1:B3,"missing")	Custom if_not_found value is returned when no match	missing	missing	Matched
=XLOOKUP(2.5,A1:A4,B1:B4,"none",-1)	match_mode -1 (exact or next smaller item) with no exact match	20	20 2.5 has no exact match; next-smaller is 2 -> 20	Matched
=XLOOKUP("x",A1:A4,B1:B4,"none",0,-1)	search_mode -1 finds the LAST occurrence of a duplicated key	3	3 Two rows match 'x' (1 and 3); reverse search returns the later one	Matched
=XLOOKUP("a",A1:A1,B1:B1)	Degenerate 1-cell lookup/return arrays where the cell is blank	#N/A	#N/A A1 and B1 are blank; lookup value 'a' is not found	Matched
