I have been using Excel since version 0.99 (on the Macintosh)! I was voted an “MVP” (Most Valuable Professional) by Microsoft for 25 years, from 1993-2018. I’m the author of 5 Excel books, available from Amazon.com or MrExcel.com. I consult and train on all levels of Excel. I lead the New York PC User's group on Excel monthly.
