What is an VSDM file?
The .VSDM file extension is associated with Visio Macro-Enabled Drawing files used by Microsoft Visio, a diagramming and vector graphics application.
These files contain both the drawing data and any associated macros—scripts or code that can automate repetitive tasks or add custom functionalities to the diagrams.
The .VSDM format is an evolution of the earlier .VSD file format, introduced with Visio 2013 and later versions, to support the addition of macros while maintaining compatibility with Visio’s drawing capabilities.
More Information.
The .VSDM file format emerged with Visio 2013, alongside other updated file formats such as .VSDX (for standard drawings) and .VSSX (for stencil files).
The primary purpose of the .VSDM file is to enable users to create Visio diagrams that can include and execute macros.
This was a significant advancement from earlier versions where macros were not supported in Visio drawings, limiting users’ ability to customize and automate their workflow.
With the introduction of .VSDM files, users could create complex diagrams with embedded code that could handle repetitive tasks, interact with other applications, or provide advanced functionality beyond the standard features of Visio.
This capability made the .VSDM format particularly valuable in environments where automation and customized functionality were essential, such as in large organizations or specialized industries.
Origin Of This File.
Microsoft Visio is a part of the Microsoft Office suite, widely used for creating flowcharts, organizational charts, network diagrams, and other visual representations of data.
The .VSDM format was introduced with Visio 2013, part of a broader update to the file format system in Visio that included support for macros. The inclusion of macros allowed users to enhance their diagrams with custom scripting, automate tasks, and improve productivity.
The decision to support macros in Visio was driven by the need for advanced automation and customization options in diagramming tasks.
By introducing the .VSDM format, Microsoft provided users with the ability to embed VBA (Visual Basic for Applications) code directly within Visio documents, thus making the application more versatile and powerful.
File Structure Technical Specification.
A .VSDM file is a ZIP-compressed archive that contains multiple XML files and other resources used by Visio to render and manage the drawing. The structure of a .VSDM file includes:
- Drawing XML File: This file contains the main drawing data, including shapes, connectors, and other visual elements. It is typically found within the “Visio” folder inside the ZIP archive.
- Macros XML File: This file holds the VBA code and macros associated with the drawing. It is stored within the “Macros” folder in the archive. The macros are executed when the document is opened in Visio.
- Support Files: Additional files, such as images, styles, and templates used in the drawing, are included in the “Media” and “Style” folders.
- Metadata: Information about the document, such as author, creation date, and modification details, is stored in XML files within the “DocumentProperties” folder.
The .VSDM file format supports Visio’s XML-based drawing storage and integrates VBA scripting to enhance functionality. It ensures that macros can be safely executed while maintaining compatibility with Visio’s drawing features.
How to Convert the File?
To convert a .VSDM file, users may need to change it to a different format compatible with their requirements. Here are some common conversion scenarios:
- To .VSDX: To convert a .VSDM file to a standard Visio drawing file (.VSDX) without macros, open the .VSDM file in Visio, and use the “Save As” function to save it as a .VSDX file. This will remove any macros but preserve the diagram.
- To PDF: To convert a .VSDM file to a PDF for sharing or printing, open the file in Visio and use the “Save As” or “Export” function to select PDF as the output format.
- To Image Formats: For exporting diagrams as images (e.g., PNG, JPEG), use the “Save As” function in Visio and choose the desired image format.
- To Other Formats: For conversions to other formats or applications, third-party tools or online converters might be used, but ensure they support .VSDM files and handle macros appropriately.
Advantages And Disadvantages.
Advantages:
- Enhanced Functionality: The primary advantage of .VSDM files is their support for VBA macros, allowing users to automate tasks and add custom functionality to diagrams. This can significantly improve productivity and streamline complex workflows.
- Integration with Microsoft Office: Being part of the Microsoft Office ecosystem, .VSDM files are well-integrated with other Office applications, enabling users to link Visio diagrams with Excel data or Word documents.
- Backward Compatibility: Visio’s support for .VSDM files ensures backward compatibility with older versions of Visio that used different file formats, making it easier for users to transition to newer versions.
Disadvantages:
- Security Risks: Macros can potentially contain malicious code, posing a security risk if .VSDM files are opened from untrusted sources. Users must ensure that macros are from reliable sources to avoid security issues.
- File Size: The inclusion of macros and additional resources can increase the file size compared to standard .VSDX files. This might affect performance and sharing, especially with large or complex diagrams.
- Compatibility: While .VSDM files are compatible with recent versions of Visio, users of older versions or other diagramming tools may have difficulty accessing or editing these files.
How to Open VSDM?
Open In Windows
- Microsoft Visio: The primary application for opening .VSDM files is Microsoft Visio. Simply double-click the file if Visio is installed, or open it via the “File” menu in Visio.
- Visio Viewer: For viewing .VSDM files without editing, Visio Viewer can be used. It allows users to view Visio diagrams but not edit or run macros.
Open In Linux
- Online Tools: Similar to Mac, Linux users can rely on online tools to view or convert .VSDM files. LibreOffice Draw might be used to open and view Visio files, though compatibility with macros is limited.
- Virtual Machines: Running a Windows virtual machine on Linux with software like VirtualBox can provide access to Visio for opening .VSDM files.
Open In MAC
- Microsoft Visio for Mac: There is no native version of Microsoft Visio for Mac. Users can use alternatives such as Visio for the web via Office 365, or run Visio in a virtual machine or through a remote desktop connection.
- Online Converters: To view or convert .VSDM files, users can use online services or converters that support Visio files.
