What is a .vstm file?
A .vstm file is a Microsoft Visio Macro-Enabled Template (version 2013). This is a code, script or executable format.
How to open a .vstm 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 Visio Macro-Enabled Template, so software from that family is the most likely match.
How to convert a .vstm file
- Text-based code needs no conversion — just save with a different extension if a tool insists.

When a .vstm file travels over the web, servers label it with this MIME type:
application/vnd.ms-visio.template.macroEnabled.main+xmlThe technical record
