What is a .xlam file?
A .xlam file is a Microsoft Excel Macro-Enabled Add-In (version 2007). This is a code, script or executable format.
How to open a .xlam file
- VS Code opens and highlights nearly every text-based code format.
- Never run a script you didn't write or trust.
The registry records this extension against Microsoft Excel Macro-Enabled Add-In, so software from that family is the most likely match.
How to convert a .xlam file
- Text-based code needs no conversion — just save with a different extension if a tool insists.

When a .xlam file travels over the web, servers label it with this MIME type:
application/vnd.ms-excel.addin.macroEnabled.12The technical record
