John Dumoulin has never really set foot in an office. He works part time at Chick-fil-a.

But the 17-year-old from northern Virginia is the undisputed king of that bane to office workers everywhere — the spreadsheet. Dumoulin won an international competition on Microsoft Excel proficiency, earning $10,000 in prize money along the way.

Dumoulin learned about the competition after taking an IT class at school in which he earned certifications on various office software products. As it turned out, his score on the Microsoft Excel 16 certification exam was the highest in Virginia, qualifying him for a national competition in Orlando, Florida.

I would have never guessed this was a thing. I knew about Microsoft certifications but not a championship.
