Spreadsheet created by Lotus 1-2-3, part of IBM Lotus SmartSuite; organizes data in rows and columns; functions can be applied to the data in various cells, which can automatically populate the data in other cells. Lotus 1-2-3 was first developed by Lotus Development Corporation, which was bought by IBM in 1995. The "1-2-3" refers to the program's three main capabilities: 1) spreadsheet functions, 2) creating charts and graphs, and 3) basic database operations.
