Convert UOF SPREADSHEET to XLS (Excel)

The Uniform Office Format (UOF) for spreadsheets, is a Chinese open standard designed for office applications. UOF, first introduced in 2007, utilizes XML-based data and compression techniques to store information efficiently, akin to Microsoft Office Open XML and OASIS OpenDocument formats. Although not universally compatible with other formats, it is supported by various applications. This format aims to streamline the use of spreadsheets in a standardized and accessible manner.

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.
