Step 1: Download iSumsoft Product Key Finder and install it on your computer.

Step 1: Open an elevated command prompt. (Win + X, A)
Step 2: Run the ospp.vbs script and note the last five characters of the Installed product key.
The ospp.vbs script is located under the Microsoft Office program folder.
The subfolder varies depending on the Microsoft Office version, and whether you are using 32-Bit or 64-Bit Windows/Office.
Script example: Office 2016/2019 (64-bit) on a 64-bit version of Windows

How to Find Microsoft Office Product Key – FAQ
Can I view my product key in Office
No, you can not. For security reasons, the full product key isn’t displayed within the Office.
Instead, for Office 365, Office 2019, and Office 2016, you can view the Microsoft account that Office belongs to. This account takes the place of your product key and can be used to reinstall Office from the Microsoft account, Services & subscriptions page and to activate Office.
To view the Microsoft account that Office belongs to, open any Office app and go to File > Account. Look for the email address after Belongs to below the product name.
How to view my product key online
If you bought Office 365 or Office Home & Student
Your product key isn’t displayed online. If Office is prompting you for a product key, you can sign in using the Microsoft account that you used to buy and download Office.
If you bought Office Home & Business, Office Professional, and individual Office apps
Product keys for one-time purchases of Office Home & Business, Office Professional, and individual Office apps are available at the Microsoft account, Services & subscriptions page.
