Bill Jelen – Guerrilla Data Analysis Using Microsoft Excel

I spent twelve years ‘in the trenches’, working as a financial analyst for finance, accounting, marketing and operations departments of a $500 million company. Armed with a half-rate reporting tool and a spreadsheet, I was responsible for turning large amounts of data into analyses for the board room quickly and accurately. Working originally in Lotus 1-2-3 and then Microsoft Excel, I honed techniques to take massive amounts of data and produce meaningful reports in record time. These techniques are spelled out in Guerilla Data Analysis Using Microsoft Excel.

In 1998, I launched MrExcel.com, which is now one of the three most popular Excel websites with 21 million annual page views. Being MrExcel is now my full-time gig. My team has developed custom applications for hundreds of clients around the world. I enjoy entertaining a room full of accountants with my ‘Power Excel’ seminar.

When I am not Excelling, you can find me and the family under the stars enjoying a movie at one of the many drive-in theaters that still dot northeast Ohio or kayaking on the Mogadore Resevoir.
