- Description
- 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.
- An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
