ARRAYTOTEXT
Unsupported (not recognized)Category: Text · Last tested 2026-09-01
Real compatibility results for the ARRAYTOTEXT function: executed in Excel for the web, Google Sheets and LibreOffice Calc, with desktop Excel behavior from Microsoft’s official documentation (we do not run desktop Excel — Excel for the web is a different application and is executed separately). Syntax and links to that documentation are below.
Support matrix
| Engine | Documented | Live-tested | Verdict |
|---|---|---|---|
| Excel (desktop) | Yes | No — documented only | n/a |
| Excel for the web | — | Yes (recalc, 2026-09-01) | Supported, behaves as documented |
| Google Sheets | No | Yes (Drive import, 2026-08-29) | Unsupported (not recognized) |
| LibreOffice Calc | No | Yes (25.8.7.3, 2026-07-29) | Unsupported (not recognized) |
LibreOffice version history
We executed the same test cases under each LibreOffice release to show exactly when ARRAYTOTEXT’s support changed — not documentation claims, real results.
| LibreOffice version | Verdict | Tested |
|---|---|---|
| 24.2.0.3 | Unsupported (not recognized) | 2026-08-29 |
| 24.8.7.2 | Unsupported (not recognized) | 2026-08-29 |
| 25.2.0.3 | Unsupported (not recognized) | 2026-08-29 |
| 25.8.7.3 | Unsupported (not recognized) | 2026-07-29 |
Why isn't ARRAYTOTEXT working in LibreOffice?
LibreOffice Calc does not implement ARRAYTOTEXT as of 25.8.7.3 — in our
executed tests it returns a #NAME? (unrecognized function) error. This is not a typo or a
settings problem, and saving the file as .xlsx does not change it: the function simply isn’t
available yet.
The same formula is documented for Excel.
Watch the LibreOffice version support page —
we re-run every test on each new release, so it will flip to Supported here as soon as it lands.
Why isn’t ARRAYTOTEXT working in Google Sheets?
Google Sheets does not implement ARRAYTOTEXT: we imported the formula into
Sheets on 2026-08-29 and every case came back #NAME?
(unrecognized function). Sheets is a rolling service with no version to pin, so this is a
statement about the service on that date, and Google’s own
function list does not document it either. Rewrite the formula with a documented
Sheets equivalent — see the
Excel ↔ Sheets equivalents table.

Executed test cases
Excel for the web (executed 2026-09-01 via OneDrive recalculation)
These values come from Excel for the web, not from desktop Excel. They are two different implementations of the calculation engine, and this run measured only the web one: the corpus was uploaded to OneDrive as .xlsx, recalculated by Excel for the web on open, and downloaded again for readback. Excel for the web is a rolling service with no pinnable version, so the run is identified by its date. Where a value here disagrees with the Expected column — which is Microsoft’s documentation of the desktop product — we cannot tell you whether the web engine diverges from the desktop one or the documentation is wrong about both, because we do not run desktop Excel.
| Formula | Description | Result | Expected | Verdict |
|---|---|---|---|---|
| =ARRAYTOTEXT({1,2,3}) | Default (concise) format joins elements with comma+space | 1, 2, 3 | 1, 2, 3 | Matched |
| =ARRAYTOTEXT({1,2,3},1) | format=1 (strict) reproduces array-literal syntax with braces | {1,2,3} | {1,2,3} | Matched |
| =ARRAYTOTEXT({1,2;3,4}) | 2-D array literal, default format | 1, 2, 3, 4 | 1, 2, 3, 4 | Matched |
| =ARRAYTOTEXT({"a","b"},1) | Strict format quotes text elements | {"a","b"} | {"a","b"} | Matched |
Google Sheets (executed 2026-08-29 via Drive import)
Google Sheets is a rolling service with no pinnable version, so this run is identified by its date. The corpus was imported to Drive as .xlsx, recalculated by Sheets, and exported back for readback.

| =ARRAYTOTEXT({1,2,3}) | Default (concise) format joins elements with comma+space | #NAME? | 1, 2, 3 | Mismatch |

| =ARRAYTOTEXT({1,2;3,4}) | 2-D array literal, default format | #NAME? | 1, 2, 3, 4 | Mismatch |

Docs & syntax
- Excel (desktop): official documentation
Where ARRAYTOTEXT behaves differently
- Which LibreOffice version for VSTACK, TEXTSPLIT, TAKE & DROP?
VSTACK, HSTACK, TEXTSPLIT, TAKE and DROP return #NAME? in LibreOffice 24.2, 24.8 and 25.2 - our executed runs show all fourteen working only from 25.8.7.3. Full version map by wave. - LAMBDA, MAP & SCAN: Excel vs LibreOffice
Excel evaluates LAMBDA(x,x*2)(5) as 10; LibreOffice returns #VALUE! for inline lambdas and #NAME? for MAP, SCAN and REDUCE. What breaks and how to rewrite it.
