- 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 XML file is an XML (Extensible Markup Language) data file. It is formatted much like an .HTML document, but uses custom tags to define objects and the data within each object. XML files can be thought of as a text-based database.
