What Is JSON to XML Conversion and Why Do Developers Need It?

JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are the two most widely used data interchange formats. While JSON dominates modern web APIs and JavaScript applications, XML remains critical in enterprise systems, SOAP APIs, Android layouts, RSS feeds, SVG graphics, and configuration files like Maven's pom.xml and .NET's Web.config.
