Which MIME types are related to file extension ".vsdx"?
The .vsdx file extension is associated with 4 MIME types:
application/vnd.ms-visio.drawing, application/vnd.ms-visio.drawing.main+xml, application/vnd.visio, application/vnd.visio2013.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .vsdx Files
VSDX files are diagram files used by Microsoft Visio.
They rely on the Office Open XML format. This means the file’s data is stored as structured XML, making it easy to manage and share.
The MIME types you see – application/vnd.ms-visio.drawing, application/vnd.ms-visio.drawing.main+xml, application/vnd.visio, and application/vnd.visio2013 – indicate different iterations and specific roles of the format. They show that these files are designed to be macro-free and are tailored for each Visio version, especially from Visio 2013 onward.
- Main Use: Creating diagrams and flowcharts, such as organizational charts, network layouts, and process flows.
- Technical Details: Utilizes an open XML structure for better compatibility and data recovery.
- Software: Primarily opened and edited with Microsoft Visio, though some other diagramming apps may offer limited support.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What program do I need to open a VSDX file?
The primary software for opening and editing .vsdx files is Microsoft Visio (version 2013 or later). However, you can also view them using the free Microsoft Visio Viewer, or edit them with third-party tools like LibreOffice Draw, Lucidchart, and OmniGraffle.
How can I open a VSDX file without owning Microsoft Visio?
If you do not have a license for Visio, you can use the free Visio Viewer provided by Microsoft to read the file. Alternatively, you can use web-based platforms like Lucidchart or open source software like LibreOffice Draw to view and make basic edits to the diagram.
What is the difference between VSD and VSDX files?
VSD is the older, binary-based format used by Visio 2010 and earlier, while VSDX is the modern format based on Office Open XML. VSDX files are generally smaller, more robust against corruption, and easier for other applications to parse than the legacy VSD format.
Can I open VSDX files on a Mac?
Yes, although there is no native desktop version of Microsoft Visio for macOS, you can use Visio for the Web in a browser. Additionally, Mac-native applications like OmniGraffle and LibreOffice can open and edit VSDX files.
Why can't I open a VSDX file in Visio 2010?
Visio 2010 predates the VSDX format, which was introduced with Visio 2013. To open these files in Visio 2010, you must install the Microsoft Visio Compatibility Pack, which allows older versions to read the newer XML-based structure.
Are VSDX files safe from macro viruses?
Generally, yes. The .vsdx extension strictly indicates a macro-free file. If a Visio diagram contains VBA macros, it must be saved with the .vsdm extension instead, making .vsdx a safer format for sharing.
How do I convert a VSDX file to PDF?
In Microsoft Visio, go to File > Export or Save As and select PDF as the file type. If you do not have Visio, many online conversion tools or LibreOffice Draw can export the diagram to PDF format.
What is the correct MIME type for VSDX files?
The standard MIME type for VSDX files is application/vnd.ms-visio.drawing. However, you may also encounter application/vnd.visio2013 on some systems. For a complete list of related types, check the Visio MIME types entry.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
