Nothing fancy, simply a reconstruction of a fake date from the month number provided, and reformat it with the FORMAT function.

Of course as an alternative you can go the old-fashioned way and write a SWITCH statement and hard-coded for the 12 months. It's up to you.

You can try this too:

Month name = FORMAT('Table'[date_column], "MMM")

If you use single quotes in 'MMM', it doesn't work. Ensure to use ""
