The 123 file format is a proprietary file format developed by the Lotus Development Corporation for use with its Lotus 1-2-3 spreadsheet software. It is a binary file format, which means that it stores data in a binary format that is not easily readable by humans.
123 files contain data and formatting information for a Lotus 1-2-3 spreadsheet, including cell values, formulas, formatting rules, and other details. They can be created and edited using Lotus 1-2-3, and can be saved and shared with other users who have access to the software.
123 files are not widely supported by other spreadsheet software, and may require the use of specialized tools or converters in order to open and view the data they contain.
