HAS, HASANY, and FLATTEN are not enabled in the production Excel for Mac 16.114 build; to try them now, install Excel through Microsoft’s Microsoft 365 Insider/Beta channel rather than reinstalling the same production release.^1^
Switch to an Insider build
Since updating and reinstalling production Excel did not help, check the installation source and channel:
- In Excel, select Help > Check for Updates.
- In Microsoft AutoUpdate, select Advanced.
- Under Update Channel, select the available Insider/Beta option.
- Accept the Insider agreement, select Check for Updates, and install all offered updates.
- Restart Excel and type
=HAS, =HASANY, or =FLATTEN in a blank cell. If the function appears in formula autocomplete, it has reached your account and build.
Microsoft documents Insider as the early-access route for preview features; displayed channel names can vary by account, build, and enrollment status.^2^
If no Insider/Beta option appears
Your Excel installation may be from the Mac App Store. App Store builds use the production channel and cannot receive Insider builds; Insider versions must be installed directly from Microsoft.^3^
To identify the installation:
- Open Finder > Applications.
- Control-click Microsoft Excel.app, then select Show Package Contents.
- Open Contents.
- If
_MASReceipt exists, it is the Mac App Store edition.^4^
In that case, remove the App Store installation and install Microsoft 365 directly from Microsoft before enrolling in Insider. Back up unsaved local workbooks first. Your Microsoft 365 Personal subscription is eligible to activate the directly downloaded apps.
What version 16.114 indicates
Version 16.114 (Build 26101123) is the October 14, 2026 production release. Its published Excel entry contains quality and performance improvements but does not list these functions as a production feature.^5^
Therefore:
- There is no workbook preference that turns these functions on in production 16.114.
- Reinstalling 16.114 will not add them.
- Even on Beta, feature rollout can be staged, so installation of the newest Beta build does not guarantee immediate availability.
- If the functions remain absent after installing Beta, use Help > Feedback in Excel and wait for the feature to reach that build/account.
- Avoid sharing a workbook that depends on these functions with production-channel users until general availability; unavailable functions can appear with
_xlfn. or return #NAME?.^6^
The available Microsoft material does not yet provide authoritative production documentation for the final syntax, so examples from preview articles may change before general availability.
