Whether you use Microsoft Office for personal or professional purposes, sometimes it can be important to know which version of Office you’re using.

Here we present you several ways to find out your Office version with just a few clicks.

How to check your Office version quick guide

  1. Click File in the top left in the ribbon.
  2. In the sidebar on the left, click on Account.
  3. On the right under Product Information, you will see your Office version.

The Office serial number, which is also commonly referred to as the product key, can’t be found out using this method. To find your Office product key, special additional tools from third-party providers are needed.

Find out the last used Office version of a document

In each document, Microsoft Office stores the version number of the Office program that was used to create and save the document. Based on this number, Office recognises whether the document can be opened with a certain version and whether possibly incompatible macros or templates are included.

However, this version number is not displayed directly in the properties of the document. Luckily, there’s a trick to finding it:

  1. First, create a backup of the document and change the file extension from .docx to .zip. If you do not see the file extension listed, you can have it displayed under ‘View’ (Windows 8 to 10) or ‘Show’ (Windows 11).
  2. Double click the zip file to open it.
  3. Open the docProps folder and launch the file app.xml.
  4. In the penultimate line under <AppVersion>, you will find the office version with which this file was saved.

Find your Office version without starting Office

If an Office program like Word can’t be launched, because maybe the program is corrupt, you can look up the Office version directly in the program file. This method also works for local networks to find out what version of Office is installed on a different computer.

Step 1: In explorer, switch to This PC and go to Program Files > Microsoft Office > Office. Step 2: Here you will find the subfolder OfficeXX with XX indicating the version number, for example 16 for Office 2016. Step 3: There may also be several folders with different version numbers if you have additionally installed macros or add-ins from other Office versions. In this case, search for the file WINWORD.EXEand right-click on it. SelectProperties from the context menu.
