To share the OFFICEUI file, you'll export the file, which creates the .EXPORTEDUI file. Select File → Options → Customize Ribbon, make your changes, select Import/Export, choose Export all customizations, name the file, choose a save location, and click Save.

To import the EXPORTEDUI file (in the same window as described above), click the Import/Export button, choose Import customization file, select the file, and click Open.

NOTE: The OFFICEUI file was introduced with Microsoft Office 2010 but is compatible with later versions of Office.
