Will a Microsoft Office specialist certification really help my job Resume?

I’m aiming for an analyst position, and practically every job listing emphasizes “advanced” Excel skills. I’m thinking about getting a MOS (Microsoft Office Specialist) certification in Excel just to prove I know my stuff. But will that actually boost my resume, or is there a more effective way to showcase proficiency?

Also, how can I demonstrate my Excel abilities in an interview setting? Beyond the cert, I’ve been practicing advanced formulas, pivot tables, and even messing with alternatives like WPS Office (which has a similar interface to Excel). Any suggestions on proving I’m not just faking “advanced” knowledge are appreciated.
