How to Export Excel LAMBDA Functions to an AFE Module
Question details
The user wants to export workbook-level LAMBDA functions, including their comments, directly into an Advanced Formula Environment (AFE) module.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Managing complex custom functions using the Advanced Formula Environment add-in.
- Observed behavior
- Excel stores workbook-level LAMBDA functions as defined names but lacks a native tool to bulk export these definitions into an AFE module.
Before proceeding, ensure your Advanced Formula Environment add-in is updated to the latest version, and create a backup of your workbook to prevent accidental deletion of your defined names during manual migration.
Consult GitHub Workarounds for AFE
Since there is no native export feature, the best approach is to check the AFE GitHub repository for community workarounds or to submit a feature request.
Currently, Excel does not offer a built-in method to migrate workbook-level defined names (LAMBDA functions) directly to the Advanced Formula Environment (AFE) module.
Navigate to the Microsoft Garage GitHub repository for the Excel Advanced Formula Environment.
Look for the specific issue thread titled 'Import module from Name Manager'. Here, you can find scripts or manual steps shared by the developer community.
If you have advanced import or export requirements, submit a new feature request or comment directly on the GitHub page to reach the development team.
