XML to JSON Converter

Quick answer: XML to JSON Converter is a free online tool that lets you convert XML to JSON — or flip the direction and turn JSON back into well-formed XML. Attributes, repeated elements, and text nodes are all handled correctly. It works instantly with no signup or download — everything runs privately in your browser.

What is the XML to JSON Converter?

XML and JSON are the two dominant formats for structured data: XML rules configuration files, SOAP services, and document formats, while JSON dominates web APIs and JavaScript. This XML to JSON converter translates between them in both directions, so legacy XML feeds can be consumed by modern JSON tooling — and JSON payloads can be turned back into XML for systems that still require it.

The conversion follows sensible, documented rules. XML attributes become @-prefixed properties (id=”bk101″ becomes “@id”: “bk101”), repeated sibling elements become arrays, and mixed text content lands in a #text property. Going the other way, @-prefixed keys turn back into attributes and arrays become repeated elements, producing well-formed, indented XML. Round-tripping XML → JSON → XML preserves your data faithfully.

Everything runs locally in your browser using the native XML parser — no uploads, no size games, no signup. That makes it safe for production configs and API payloads containing internal hostnames, keys, or customer data you would never paste into a server-side converter.

How to use the XML to JSON Converter

  1. Paste your XML (or JSON, if converting the other way) into the input box.
  2. Choose the direction: XML → JSON or JSON → XML.
  3. Pick your indentation style for readable output.
  4. Click Convert. Invalid input produces a clear error message pointing at the problem.
  5. Copy the result or download it as a .txt file for your code or config.

XML to JSON Converter use cases

Consuming legacy XML APIs

SOAP services and old RSS-style feeds speak XML; your frontend speaks JSON. Converting the response here lets you prototype against realistic data without writing a parser first.

Migrating configs to JSON

Moving app configuration from XML files to JSON? Convert the existing files, review the @attribute and #text mappings, and you have a faithful starting point instead of a hand-retyped guess.

Generating XML for legacy systems

Some enterprise systems still only accept XML. Draft the payload as JSON — far easier to write by hand — then convert it to well-formed XML for the integration.

Debugging API payloads

Paste a confusing XML response, convert it to pretty JSON, and the structure becomes scannable in seconds. Attributes, nesting, and repeated elements all show up exactly where they belong.

Tips

  • Repeated sibling elements (<item> appearing twice) become JSON arrays automatically — that is the correct mapping, not a bug.
  • XML attributes are prefixed with @ and text content with #text, so nothing is silently dropped in either direction.
  • If conversion fails, the error names the problem — usually an unclosed tag or a stray & that needs escaping as &amp;.
  • For huge documents (tens of megabytes), a streaming parser in your own code beats any browser tool; this converter targets everyday payloads.

Frequently asked questions

How are XML attributes converted?
Attributes become properties prefixed with @ — becomes {"book": {"@id": "bk101", ...}}. Converting back, any @-prefixed key turns into an attribute again, so round-trips preserve them.
What happens to repeated XML elements?
They become JSON arrays. Two siblings under produce "book": [ {...}, {...} ]. A single stays a plain object. This matches how every major XML-to-JSON library behaves.
Where does element text content go?
A leaf element like Midnight Rain becomes a plain string. When an element has both attributes and text, the text lands in a #text property so nothing is lost: {"@id": "bk102", "#text": "..."}.
Can I convert JSON back to XML?
Yes — switch the direction to JSON → XML. @-prefixed keys become attributes, arrays become repeated elements, and you get indented, well-formed XML with an XML declaration.
Why did my XML fail to convert?
Almost always malformed XML: an unclosed tag, mismatched nesting, or a raw & or < in text content (they must be & and <). The error message points at the offending region — fix it there and retry.
Is it safe to convert sensitive XML here?
Yes. Parsing happens entirely in your browser with the native DOMParser — your data is never uploaded, stored, or logged. No signup, no server, no trace.
Does it handle XML namespaces?
Namespace prefixes are preserved as part of tag and attribute names (e.g. soap:Envelope stays soap:Envelope). Namespace declarations (xmlns attributes) convert like regular attributes.
Can I use this on my phone?
Yes, it works in any modern mobile browser. Pasting a payload and converting it takes seconds, with copy and download working the same as desktop.
