JSON to XML
Convert JSON to XML format with customizable indentation and optional XML declaration. Runs entirely in your browser.
What does this JSON to XML converter do?
This tool converts JSON data structures into XML format, transforming key-value pairs into nested XML elements while preserving the data hierarchy.
How does the conversion process work?
The tool parses JSON and recursively converts each key-value pair into XML elements. Objects become nested elements, arrays create repeated elements with the same tag name, and primitive values become text content.
What indentation options are available?
You can choose between spaces (2 spaces per level), tabs, or no indentation for compact output.
What does the XML declaration option do?
It adds <?xml version="1.0" encoding="UTF-8"?> at the beginning of the output, which is the standard XML declaration required by many XML parsers.
How are numeric keys handled?
Numeric keys (like array indices in objects) are prefixed with "row-" since XML element names cannot start with a number according to XML specifications.
Can I convert large JSON files?
Yes, the tool handles large JSON files efficiently. All processing happens locally in your browser, so there are no file size limits imposed by servers.
Is my data safe and private?
Yes. All processing happens locally in your browser. No data is sent to any server, ensuring complete privacy and security.
What are common use cases for JSON to XML conversion?
Common uses include integrating with legacy systems that require XML, generating configuration files, data exchange between different platforms, and working with SOAP web services.
Does the tool validate JSON input?
Yes, the tool validates JSON syntax before conversion and provides clear error messages if the JSON is malformed.
Can I customize the root element name?
The tool automatically creates a root element based on the JSON structure. For objects, it uses "root" as the default element name.
How are special characters handled?
Special characters like <, >, and & are automatically escaped to their XML entity equivalents (<, >, &) to ensure valid XML output.
Is this tool free to use?
Yes, this JSON to XML converter is completely free with no usage limits, no registration required, and no watermarks on output.
How to Use JSON to XML
Convert JSON documents into well-formed XML without leaving your browser. The whole conversion runs locally, so nothing you paste is ever uploaded.
- Paste your JSON into the input editor; the XML result appears immediately in the output panel.
- Set the wrapper element name in the "Root:" field, for example data or response.
- Under "Indentation:" pick Spaces for two-space nesting, Tabs for editor-friendly output, or None for a single-line document.
- Enable "Add XML meta tag" to prepend the XML declaration to standalone files.
JSON keys become XML element names, so keys with spaces or special characters get sanitized — rename them in the source JSON if you need exact tag names.
