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.
The FODS (OpenDocument Flat XML Spreadsheet) file format is a type of document file designed for storing spreadsheet data in a single, uncompressed XML file. It is part of the OpenDocument Format (ODF) family, an open standard for document files. Unlike the more common ODS format, which packages various components of the spreadsheet (such as XML files, metadata, and images) into a single, compressed ZIP file, FODS files store all the spreadsheet information in a flat XML file.
