Updated: 10/02/2017 by Computer Hope
VisiCalc was the first spreadsheet software program developed by Dan Bricklin and programmed by Bob Frankston in 1978. It was written in the Apple BASIC language on an Apple 2 computer. VisiCalc was eventually sold to Lotus Development Corporation and was the basis for the development of the Lotus 1-2-3 spreadsheet application in 1983.
