Description | 123 Lotus is a file format used by the Lotus 1-2-3 spreadsheet program, which was popular in the 1980s and 1990s. The 123 Lotus format is used for storing data in a tabular format, allowing users to easily organize and manipulate large sets of data. The 123 Lotus format is based on a system of worksheets, which consist of rows and columns that can be used to store and manipulate data. The format includes features such as formulas, macros, and charts, which allow users to perform complex calculations and generate graphical representations of their data. Although the Lotus 1-2-3 program is no longer as widely used as it once was, the 123 Lotus format remains a common file format for older spreadsheets and datasets. While newer spreadsheet programs such as Microsoft Excel have largely supplanted Lotus 1-2-3, many users still maintain legacy datasets in the 123 Lotus format and may need to convert these files to more modern formats in order to use them with newer software. In summary, 123 Lotus is a file format used by the Lotus 1-2-3 spreadsheet program for storing data in a tabular format. While the program is no longer widely used, the 123 Lotus format remains a common file format for older datasets and may require conversion for use with modern software. |
