UNICODE
Supported, behaves as documentedCategory: Text · Last tested 2026-09-01
Real compatibility results for the UNICODE 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 ā documented only | n/a |
| Excel for the web | — | Yes (recalc, 2026-09-01) | Supported, behaves as documented |

LibreOffice version history
We executed the same test cases under each LibreOffice release to show exactly when UNICODE’s support changed — not documentation claims, real results.
| LibreOffice version | Verdict | Tested |

| 24.2.0.3 | Supported, behaves as documented | 2026-08-29 |
| 24.8.7.2 | Supported, behaves as documented | 2026-08-29 |
| 25.2.0.3 | Supported, behaves as documented | 2026-08-29 |
| 25.8.7.3 | Supported, behaves as documented | 2026-07-29 |
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 |
|---|---|---|---|---|
| =UNICODE("A") | Basic Latin character code point | 65 | 65 | Matched |
| =UNICODE("Ć©") | Code point of an accented character beyond basic Latin (U+00E9) | 233 | 233 | Matched |
| =UNICODE("š") | Code point of a supplementary-plane emoji character (U+1F600), the inverse of the UNICHAR_astral_emoji case | 128512 | 128512 | Matched |
| =UNICODE("") | Empty text has no first character to inspect -> #VALUE!. Verified via https://support.microsoft.com/en-us/office/unicode-function-adb74aaa-a2a5-4dde-aff6-966e4e81f16f (documented error handling: invalid/partial character data returns #VALUE!) | #VALUE! | #VALUE! | 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.
