Extract text from Visio macro-enabled stencils (VSSM)
To convert VSSM stencils to another format, you need Microsoft Visio or other Vector Image software.
To convert other file formats to the "Visio Macro Stencil" file type, you need software like Microsoft Visio or a similar tool.
A .VSSM file is a Microsoft Visio Macro-Enabled Stencil File. It stores a customized collection of master shapes, lines, and connectors used to build professional diagrams. Unlike standard stencils, it contains embedded VBA (Visual Basic for Applications) macros designed to automate repetitive drawing tasks or enforce specific diagram logic.
The primary software used to create and open these files is Microsoft Visio, a commercial vector graphic and diagramming application. The format is based on the Open Packaging Conventions (OPC) standard, meaning a .VSSM file is essentially a ZIP archive containing XML architecture files, shape media, and a compiled binary file (typically vbaProject.bin) holding the executable code.
This format presents significant real-world challenges for users. It is highly proprietary and requires a paid desktop subscription to Microsoft Office. Because it contains executable macros, .VSSM files trigger security warnings and are frequently blocked by corporate firewalls or email filters due to malware risks. Furthermore, there is no native Visio desktop application for macOS, leaving Apple users unable to open these stencils natively.
Users frequently need to convert these files to safer, universally readable formats. Converting to a macro-free VSSX removes the security risk. If you only need to view the shapes, extracting them to SVG (Scalable Vector Graphics) or PDF is the most reliable solution. Be aware that exporting to these standard formats will permanently delete all automated VBA scripts.
Converting a .VSSM file is technically difficult because standard online converters cannot render proprietary Microsoft Visio shapes or process embedded executable scripts. If our analysis detects supported underlying formats, we can extract text, embedded images, and help you access the file contents safely.
Convert.Guru analyzes your VSSM file, detects the exact format, and lets you read the text inside.
If you want to convert VSSM file to , you can use Microsoft Visio or similar software from the "Macro-Enabled Shape Stencil Storage" category. In the File menu, look for Save As… or Export….
To convert files to VSSM, try Microsoft Visio or another comparable tool in the "Macro-Enabled Shape Stencil Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our VSSM converter.
