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 Although XLS has been replaced by XLSX as the default format, many legacy systems and applications still rely on XLS for data exchange.

CSV (Comma-Separated Values) is a simple text file format used for storing tabular data, widely used for data exchange between databases, spreadsheet software, and data analysis tools. Each field is separated by commas, and each line represents a record. CSV files are easy to create and edit, making them suitable for various applications such as data import/export, batch processing, and data sharing.
