- Description
- Lotus Worksheet (wk1) is a file type used by the Lotus 1-2-3 spreadsheet application. It is a binary file format used to store worksheets, which can contain numerical and textual data, as well as formulas, charts, and images. It is now considered an obsolete file type and is replaced by the newer xlsx format.
- 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.
