XLS is the early binary file format used by Microsoft Excel for storing spreadsheet data. It is widely used in data analysis, financial management, and business reporting. Unlike the modern XLSX format, XLS uses binary encoding and supports basic formula calculations and charts. Although XLS has been replaced by XLSX as the default format, many legacy systems and applications still rely on XLS for data exchange.
