XML to JSON Converter
Bidirectional XML/JSON conversion with real-time preview. [NEW-2026-06-08]
XML to JSON Converter — Free Online Tool
Convert XML to JSON and JSON to XML instantly with real-time preview. XML attributes are preserved with @ prefix notation, nested structures are accurately mapped, and mixed text/element content is handled correctly. Perfect for API developers, DevOps engineers, and anyone working with XML-based data feeds.
How it works
Paste your XML (or JSON) into the input panel and the conversion runs in real-time as you type. XML → JSON uses the browser's native DOMParser for rock-solid parsing — no regex hacks. JSON → XML rebuilds a well-formed XML document. All processing is done locally in your browser — your data never leaves your device.
Developer workflow tip
Pair this tool with our JSON Formatter to clean up the output, or with XML Formatter to prettify your XML before conversion. Use JSON Diff to compare the round-trip result against your expected schema, and YAML to JSON for YAML configs.
Privacy & security
Your data is never uploaded to any server. All conversion runs entirely in your browser using the DOM API. This is especially critical when converting configuration files or sensitive data payloads — nothing leaves your machine.

FAQ
Is this tool free to use?
Yes. The tool is free to use in your browser and does not require an account.
Do I need to install anything?
No. The conversion runs in a normal modern browser, so you can use it on desktop or mobile without installing extra software.
Is my data uploaded to a server?
No. All processing happens locally in your browser. Your XML, JSON, and any sensitive data never leave your device.
Does it preserve XML attributes?
Yes. XML attributes are converted to JSON using @ prefix notation (e.g. @class), which is a common convention in xml2js libraries.
Can I convert deeply nested XML?
Yes. The tool handles any nesting depth. Elements with the same tag name at the same level are grouped into arrays.
Does it handle XML namespaces?
The basic converter strips namespace declarations for simplicity. For advanced namespace handling, consider using a dedicated XML processor.
