File format conversion is the process of changing a file from one format to another to ensure compatibility with software, systems, or devices, while keeping the structural content of the file intact.

Specially developed programs and online tools are created to handle file format conversion effectively. These tools provide a simple interface to select the XSS file, set the XLSX format, and begin conversion.
