What is MIME type "application/vnd.ms-word.document.macroenabled.12"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

The MIME type application/vnd.ms-word.document.macroenabled.12 is specific to Microsoft Word files that allow macros. These files can execute built-in scripts to automate tasks and custom processes.
Macros are small programs typically written in VBA.

This MIME type mainly applies to documents like DOCM. Other Word formats—such as DOCX, DOC, DOTX, DOT, and DOTM—offer different capabilities and may not support macros.

This MIME type distinguishes macro-enabled documents for both functional and security reasons:

• Automation: Enables repetitive tasks to run automatically.
• Customization: Embeds advanced business logic and formatting.
• Interactivity: Provides additional features not available in standard documents.
• Integration: Supports linking with external applications and systems.

Be cautious: Macros can also run harmful code. Only enable them from trusted sources.
