Think of the Microsoft Office software you are familiar with, which will most likely include Excel, Word, PowerPoint, Outlook, Access, OneNote, OneDrive, and/or Teams.
List them in your resume’s skills section.
If you are familiar with all of them, you can simply state Microsoft Office Suite (or use the job ad’s terminology).
If they are highly relevant to the job you are applying for, you can also list your Microsoft Office skills under responsibilities in your professional experience section.
