JSON to XML

JSON object to XML elements with configurable root name.

{{ jsonToXml.message }}

Overview

XML (eXtensible Markup Language) appeared as a W3C recommendation in 1998 and dominated data exchange between systems for over a decade. Before JSON became popular in the early 2000s, almost every enterprise integration went through XML: SOAP services, WSDL contracts, ebXML, XPath queries, and XSLT transformations. Banking systems, ERPs, government APIs, and SAP integrations still depend on XML today.

The fundamental structural difference between the two formats is that XML has no native data types: all content is text, and interpreting a value as a number, date, or boolean is left to an XSD schema or the reading application. JSON, on the other hand, directly recognizes string, number, boolean, null, object, and array. XML also supports attributes, comments, namespaces, and mixed content (interleaved text and child elements) — features that JSON simply does not have.

Converting JSON to XML makes sense mainly in three scenarios: integrating with legacy systems that only accept SOAP or XML Schema as a contract; generating RSS or Atom feeds; and using XML-native technologies such as XSLT for transformations and XPath for queries. In those cases, starting from an existing JSON and converting it is faster than building the XML from scratch.

This tool converts JSON to XML directly: object keys become element names, primitive values become text content, and arrays produce repeated elements with the same tag name. The root element name is configurable. For XMLs that require namespaces, attributes, comments, or XSD validation, the output serves as a starting point that you refine in your own code.

Technical deep dive

Common questions summarized

  • What is this tool for?: It runs fully in your browser: useful to validate, format, or convert data in everyday development.
  • Are my inputs sent to a server?: Processing happens locally with JavaScript. We do not store what you paste into the text areas.
  • Can I use this for real production data?: Use at your own risk. For secrets (passwords, tokens), prefer controlled environments and your company policies. And always review the generated contents. Never trust blindly things you see on the internet.

Tool guide

  • What JSON is Hierarchical data in key–value syntax.

  • What XML is XML (eXtensible Markup Language) describes documents with nested tags, attributes, and text. It underpins SOAP, RSS, many legacy config formats, and enterprise integrations.

  • What the converter does Maps objects and arrays to XML elements with a configurable root name; primitive values become element text.

  • Why use it Adapt modern JSON payloads to XML-only systems, integration tests, and message prototypes.
