MSO file extension - Microsoft Organization Chart chart data

What is mso file? How to open mso files?

File type specification:

Document file type icon Document file type

Microsoft Office file type icon Microsoft Office file type

mso file icon: mso filetype icon

The mso file extension is primarily related to Microsoft Organization Chart, a tool that installs a separate application to create and edit organization charts that is provided by Microsoft since PowerPoint 95.

Up until  Microsoft Organization Chart 2.0 it was a separate program, but now is available Organization Chart Add-In for Microsoft Office.

The mso file contains an organization chart, which can be imported to any Office document as an object.

Although the the Microsoft Organization Chart is integrated to latest versions of Microsoft Office, it is not installed by default. You have to manually install it during the installation process (or add it in later via reinstall / change). You can find it under PowerPoint items.

Users can also create organization charts in Microsoft Visio without the Organization Chart Add-In installed. But these are saved in different format.
