Spreadsheets refer to programs that are used for applications involving numerical analysis, number crunching, graphical output, and “what-if” scenarios.
The first electronic spreadsheet was VisiCalc, introduced in 1978 for Apple II computers. Since then, the spreadsheet has become an essential tool for professionals. In the early 1980s, Lotus introduced its versatile, easy-to-use 1-2-3 for the IBM PC. Today, there are other powerful spreadsheet packages on the market, such as Microsoft’s Excel.
