This tool converts any valid JSON object or array into well-formed XML. Arrays are converted to repeated <item> elements with index attributes. Null values get a null="true" attribute. Booleans are serialized as text true/false. Everything runs in your browser — no data is ever sent to a server.
Yes. All conversion happens entirely in your browser using PHP on the server — no JSON data is stored or logged. The conversion is done on-the-fly and discarded immediately after the response is returned.
JSON arrays are converted to repeated <item> child elements, each with an index attribute indicating their position (e.g., index="0", index="1"). This preserves array ordering in the XML output.
JSON null values are represented as an element with a null="true" attribute and no text content. For example, "key": null becomes <key null="true"/>.
Yes, this tool handles large JSON payloads. For very large files (several MB), conversion may take a second or two. There's no artificial size limit imposed by the tool itself.
XML element names must follow strict naming rules. If a JSON key contains characters that are invalid in XML element names (e.g. starts with a number or contains spaces), the converter falls back to using <item> as the tag name to ensure valid XML output.
Yes! Use the "Root Element" input above the editor to set any valid XML tag name as your root wrapper. The default is root. Only alphanumeric characters, underscores, and hyphens are allowed.
Absolutely. Nested objects are recursively converted to nested XML elements. Deep hierarchies are fully supported, preserving the complete structure of your original JSON data.
Yes. Select "Minified" from the indent dropdown to receive compact XML output without any extra whitespace or newlines between elements — ideal for reducing payload size.
Converting data between JSON and XML formats is one of the most common tasks in modern software development. Whether you're integrating with a legacy SOAP-based service, preparing data for an XSLT transformation pipeline, or simply need to inspect your JSON data in a different structural format, this free browser-based tool makes the process instant and effortless.
JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format. Originally derived from JavaScript object syntax, it has become the de facto standard for web APIs, configuration files, and data storage. JSON supports six data types: strings, numbers, booleans (true/false), null, arrays (ordered lists), and objects (key-value maps). Its simplicity and native browser support make it the go-to format for modern web development.
XML (eXtensible Markup Language) is a markup language that defines rules for encoding documents in a format that is both human-readable and machine-readable. XML predates JSON and remains widely used in enterprise software, document formats (like DOCX and SVG), RSS/Atom feeds, SOAP web services, and configuration systems (like Maven's pom.xml or Android's layout files). XML's schema validation, namespace support, and transformation capabilities via XSLT make it the preferred choice in many enterprise and document-centric workflows.
Converting JSON to XML involves mapping JSON's data types and structures onto XML's element-based model. Here's how each type is handled by this tool:
<item> elements under the parent, each with an index attribute to preserve ordering.true or false.null="true" attribute.<item> for well-formedness.Despite JSON's dominance in new development, there are plenty of legitimate reasons to convert JSON to XML:
For the best results when using this converter, keep these practices in mind:
root, something like users or config makes the XML more self-documenting.Understanding the strengths of each format helps you make better architectural decisions:
<!-- -->); JSON does not (though JSONC and JSON5 extensions add this).This JSON to XML converter is particularly useful in these development scenarios:
This tool runs server-side PHP conversion on a stateless request — your JSON data is parsed and the resulting XML is returned in the response. No data is persisted, logged, or shared. The conversion is completely ephemeral. For sensitive production data, you can also implement the same conversion logic locally using any JSON/XML library in your language of choice.
