XML (Extensible Markup Language) uses verbose hierarchical markup encoding and is best for enterprise systems, SOAP APIs, document formats like DOCX and SVG. JSON (JavaScript Object Notation) uses human-readable structured data encoding and excels at APIs, configuration files, and data exchange between web services. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Transforms well-formed XML into JSON with xml2js (explicitArray off, attributes merged — no prefixed keys): repeated elements become arrays automatically, single elements stay plain values.
APIs, configuration files, and data exchange between web services.
