Convert GNUMERIC to SLK

The GNUMERIC file extension, is associated with the Gnumeric Spreadsheet program, part of the GNOME Free Software Desktop Project. Developed by Miguel de Icaza and first released in 2001, Gnumeric is a free, open-source spreadsheet application designed to replace proprietary software like Microsoft Excel. The GNUMERIC format is based on XML and compressed with gzip, ensuring efficient data storage and compatibility with various file formats. It is widely used for data analysis, statistical tasks, and scientific applications due to its accuracy and comprehensive features.

An SLK file, standing for Symbolic Link File, is a specialized file type used primarily in spreadsheet applications to facilitate data exchange. Originally introduced by Microsoft for its Multiplan spreadsheet program in the 1980s, the SLK format was later adopted by other spreadsheet software due to its simplicity and efficiency. These files are composed of ASCII text and include symbolic references to cells, allowing for easy parsing and manipulation of spreadsheet data. The primary use of SLK files is to enable seamless data transfer between different spreadsheet programs, ensuring compatibility and preserving the integrity of the data during exchange.
