What is a XLS file?
XLS is the proprietary spreadsheet format used by Microsoft Excel prior to the introduction of XLSX in 2007. It uses a binary file structure and supports formulas, charts, macros, and formatting.
XLS files remain widely compatible and are still used in many organizations. However, XLSX offers better performance and security.
How to open XLS files
XLS files can be opened using Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications. They support charts, formulas, and formatting.
To ensure compatibility and security, convert XLS to XLSX or ODS using AnyConv or within Excel itself.

What is a XML file?
XML (eXtensible Markup Language) is a flexible, structured data format used to store and transport information. It uses custom tags to define and organize content, making it both human- and machine-readable.
XML is widely used in web development, configuration files, and data exchange between systems. It serves as the foundation for many other formats like RSS, SVG, and SOAP.
How to open XML files
XML files can be opened with any text editor or code editor, such as Notepad++, Visual Studio Code, or Sublime Text. Web browsers also render them in a tree structure.
To make XML content usable, convert it into formats like CSV or JSON using AnyConv or specialized parsers.
