Even though JSON is now the preferred data format for web applications, XML remains vital in many areas of technology. Its structured, self-descriptive nature makes it ideal for enterprise systems and legacy applications that require consistent, validated data.
Examples of where XML is still widely used include:
Cloud platforms such as Amazon Web Services (AWS) and Microsoft Azure continue to use XML in configuration files and metadata storage. XML’s precision and extensibility keep it relevant even as newer formats gain popularity.
Understanding XML gives developers insight into how structured data moves between systems. It may not be as flashy as modern frameworks, but it remains the foundation for many technologies that power the web today.
