.VSDX File Extension
What is a VSDX file?
A VSDX file is a drawing created by Microsoft Visio, an application for creating drawings and technical illustrations. It stores shapes, lines, text, and other objects arranged together on a free-form canvas. VSDX files are typically used for saving flowcharts, process diagrams, organizational charts, and other types of drawings.
Microsoft introduced the VSDX format with the release of Visio 2013. It replaced the older .VSD binary format and .VDX XML format used by Visio 2010 and earlier. Visio 2013 and later versions still support VSD and VDX files.
The VSDX format uses Open Packaging Conventions (OPC), which is based on XML and uses a .ZIP container to package all the drawing contents. VSDX files can be classified as "archives" or "packages." They contain "document" parts, which include the content and metadata of the VSDX file, and "relationship" parts, which include images and text files.
Microsoft Visio is primarily used to create diagrams and store them in the VSDX file. Some other files used by Visio include the .VSDM file to store macro-enabled drawings, .VSTX files to store templates, .VSTM files to store macro-enabled templates, .VSSX files to store stencils, and .VSSM files to store macro-enabled stencils.
How do I open a VSDX file?
You can open, edit, save, and convert VSDX files with Microsoft Visio (Windows). You can also open VSDX files with Draw, which is included in the free LibreOffice suite (multiplatform), CS Odessa ConceptDraw PRO (multiplatform), Nektony VSD Viewer (iOS), and the Google Chrome web browser (with the Free Visio Viewer extension installed).
If you do not have a program that supports the VSDX format you can still view the contents of a VSDX file by renaming the .vsdx extension to .zip and unzipping the file with Microsoft Windows Explorer (bundled with Windows) or Apple Archive Utility (bundled with macOS). Keep in mind that viewing the contents of a VSDX file using this method is not the same as viewing a VSDX file with an application that supports the format.
