Microsoft Word can check for the Oxford Comma in your lists and it now uses that name in Word 2016 for Windows or Mac. Sadly, Word 2016’s options have been degraded from earlier versions.
Word 2016 can only warn you if the Oxford Comma is NOT there … good for people who prefer the ‘Comma required before last item’.
But if you don’t like the Oxford Comma, Word 2016 has removed the option to warn when the’ extra’ comma is inserted.
Oxford Comma option is OFF by default.
The default setting is ” Don’t check ” or unchecked which is why most people don’t even realize Word can check for Oxford/serial commas.
Go to Options | Proofing | Writing Styles and click the Settings button.
Word 2016 for Windows and Mac
In Word 2016 (Windows/Mac) for Office 365 subscribers, click on Writing Style settings and scroll down to ‘Punctuation Conventions’ (Windows) the very bottom of the options list (Mac).
In the Office 365 subscribers Word 2016, the name ‘Oxford Comma’ is used for the first time. It’s a simple on/off to test for the Oxford Comma and warn if it’s not there.
None of the choices available in Word 2013 or earlier.
This is a downgrading of the Oxford Comma checking from earlier versions of Word which had more nuanced options.
Word 2013 and before
The same feature in Word 2016 for perpetual licence and earlier versions of Word is called ‘Comma required before last list item’ and has better choices.
The default setting is ” Don’t check “.
Always: Oxford/Serial comma preferred. Warn if there is NOT an extra comma
Never: Oxford/Serial comma NOT required. Warn if there IS an extra comma
In other words:
Want the Oxford Comma – Always
Do NOT want the Oxford Comma – Never
Don’t care – Don’t Check
The Oxford Comma is called the ‘Comma required before last item’ by Word 2013 and previous version. It’s also known as the serial comma, series comma or Harvard comma.
It’s the comma before ‘and’ or ‘or’ at the end of a list”

Wikipedia has some good examples of where the ‘extra’ comma makes the meaning clear. For example “To my parents, Ayn Rand and God. ” could imply that the parents’ names are Ayn Rand and the Almighty. Adding a comma can eliminate that (unlikely) possibility.
