A modern Visio drawing - .vsdx, .vsdm, .vssx or .vstx - is an Office package like Word or Excel, so it carries the same document properties: the author, the last editor, the company, and a template path that quietly pins down the Office version and the account that made it. Because Visio is used for org charts, network diagrams and floor plans, that metadata often accompanies genuinely sensitive drawings.
Scan a Visio fileA scan reads Visio's document properties the same way it reads a Word file's: the author who created the drawing, the last person to save it, the company name from the Office installation, and any manager recorded in the properties. The created, modified and printed dates and the revision count sketch how long the drawing has been worked on.
The most useful field is the template path. Visio stores the template a drawing was based on as a full filesystem path, which commonly reads like C:\Program Files\Microsoft Office\Office15\... That pins down the exact Office version, and when the template lived in a user profile it can name the account. The hyperlink base (original file path) can expose a username or a network location the same way.
If the drawing was digitally signed, the signer's name and organisation are read from the certificate - identity only; the signature itself is not cryptographically verified. Custom properties set by the author or an enterprise template can carry project codes or classification labels, and any embedded OLE objects and the rendered thumbnail - which shows the drawing as it looked when saved - are flagged too. The scan reads the package metadata, not the shapes or diagram content.
File X-Ray inspects a .vsdx in your browser, lists every field, and writes a cleaned copy: the same OOXML stripper used for Word, Excel and PowerPoint blanks the core, application and custom property parts and leaves the drawing itself untouched. Visio's own File > Info > Remove Personal Information reaches further inside the shapes, so use it as well when the diagram content matters, and re-scan to confirm what remains.
This is a selection. The full field manual documents the fields read from each format.
The author and last editor, the company and any manager from the Office install, created / modified / printed dates and a revision count, a template path, custom properties, and - if the drawing was signed - the certificate signer. Because .vsdx is an Office package, it carries the same core properties as Word or Excel.
It is stored as a full filesystem path, often like C:\Program Files\Microsoft Office\Office15\... That pins the exact Office version installed, and when the template lived in a user profile it can name the account - giving away more about the machine than the drawing itself.
It can be. Network diagrams, floor plans and org charts are sensitive by nature, and the surrounding metadata - company name, author, custom properties and the template path - can identify the organisation and the person behind a drawing you assumed was anonymous. File X-Ray reads all of it in your browser, with nothing uploaded, so you can see what a .vsdx would hand over before you share it.
File X-Ray reads Visio files entirely in your browser - the file never leaves your device. For this format you can also download a clean copy with the metadata removed. Scan a file now.
