Which spreadsheet software was notably replaced by Microsoft Excel?

Lotus 1-2-3 was a pioneering spreadsheet program that played a significant role in the early development of spreadsheet software during the 1980s. It was notable for its combination of spreadsheet functions, graphical capabilities, and support for database tasks, which made it a popular choice for users at the time.

When Microsoft Excel was released, it provided a more advanced and user-friendly interface, along with better integration with other Microsoft Office applications. As Excel gained popularity throughout the 1990s, it effectively replaced Lotus 1-2-3 as the dominant spreadsheet software in the market. The transition was driven by Excel's superior features, improved performance, and the shift toward a Windows-based operating system, which was a factor in the decline of Lotus 1-2-3.

The other options represent different spreadsheet programs, but they either emerged after Excel or did not have the same level of impact in replacing Lotus 1-2-3 specifically. Quattro Pro, for instance, was a competitor but did not achieve the same level of dominance. Apple Numbers is designed primarily for macOS and iOS and is not typically seen as a direct competitor to Excel in the same way. OpenOffice Calc is an open-source tool that came later
