Convert FODS to XLS (Excel)

The FODS (OpenDocument Flat XML Spreadsheet) file extension, developed by Oracle, is used for storing spreadsheet data in a plain XML format, making it more human-readable and easier to generate automatically without a spreadsheet editor. Unlike the more common ODS format, which uses a ZIP container, FODS files are not supported by Microsoft Excel but can be opened with OpenOffice Calc. This format was introduced as part of the ODF 1.2 specifications by OASIS.

The XLS file extension, short for "Excel Spreadsheet", is a legacy format used by Microsoft Excel for storing spreadsheet data. Introduced with Excel 2.0 in 1987, it was the primary format until the introduction of XLSX in 2007. XLS files contain data organized in rows and columns, supporting formulas, macros, and various formatting options, making them essential for data analysis and financial reporting. Despite being replaced by the more robust and secure XLSX format, XLS files remain widely used in many legacy systems and applications.
