JSON to XML & XML to JSON — Free Converter
Convert JSON to XML and XML to JSON for free online. Pretty-printed XML with sensible defaults, browser-based parsing.
Convert JSON to XML and XML to JSON in one click — both directions, one tool. Pretty-printed XML output with sensible defaults (no attributes, repeated elements for arrays, UTF-8 declaration). XML parsing uses the browser's native DOMParser, so XML errors are pinpointed precisely.
Need to validate the JSON shape first? JSON Formatter. Want YAML instead? JSON to YAML.
How to Convert JSON to XML (and XML to JSON)
Pick a direction
JSON → XML (default) for sending JSON data to an XML-only consumer; XML → JSON to read XML responses in JS.
Paste your data
Drop the input into the editor and click Convert.
Copy the result
Click Copy Output, or use ⇄ Swap to feed the result back in for round-tripping.
When Do You Need This?
Legacy API integrations: Older SOAP/XML APIs are still common in finance, healthcare, and government. Convert your JSON payloads at the boundary.
Reading XML configs: Maven, Spring, IIS use XML configs. Convert to JSON for easier reading or scripting.
Quick format swaps: You have an XML file but your tool only takes JSON, or vice versa. One click solves it.
Education: Comparing the two formats side-by-side helps when explaining the trade-offs (verbosity, schema, attributes vs nesting).
Why Use PDFFlare for JSON ↔ XML?
Both Directions
JSON → XML and XML → JSON, with a swap button.

Frequently Asked Questions About JSON to XML
Some legacy APIs, banking systems, and government services still require XML. Converting JSON payloads to XML at the boundary keeps your code JSON-native while satisfying the consumer's format.
JavaScript and most modern APIs prefer JSON. Converting an XML response to JSON lets you treat it as a normal JS object instead of walking a DOM.
The current build maps everything to elements (no attributes). For attribute-heavy XML, consider post-processing with a more configurable converter — most config-style XML converts cleanly with elements only.
JSON arrays become repeated elements with the parent's name. On the way back, XML elements with the same tag name in a sequence become an array.
Not in this build. Namespaces are stripped on import; CDATA is treated as text. The tool targets typical config / data-payload XML, not document-style XML.
Defaults to <root>. If you need a specific name, wrap your JSON in a single-key object: { yourRootName: { ... } } produces <yourRootName>...</yourRootName>.
No. The conversion runs in your browser using the native DOMParser.
The browser's parser surfaces a precise error message. Fix the XML in the input pane and Convert again.
