XML to JSON Converter

The XML to JSON Converter transforms XML documents into equivalent JSON structures in a single paste-and-click interaction. XML is still everywhere — SOAP APIs, legacy enterprise systems, Microsoft Office files, RSS feeds, Android layouts, Java configuration, banking messages, and older government data feeds all rely on it. JSON dominates modern web APIs, JavaScript applications, mobile backends, and NoSQL databases. When these two worlds meet, you need a reliable converter that understands every XML quirk: attributes that live alongside elements, mixed text-and-element content, namespaces with prefixes, repeated sibling elements that must become arrays, self-closing tags, CDATA sections, and entity references.

This tool handles every XML edge case without forcing you to write custom parsing code. You paste XML, you get JSON — and more importantly, you get predictable JSON. Attributes are preserved under a clearly marked key prefix so you never lose metadata. Repeated elements are detected and grouped into arrays, even when there is only one occurrence (with a setting to force array mode for schemas you know will have collections). Namespaces can be stripped for readability or preserved for strict round-tripping. Every operation runs entirely in your browser, which means your XML never leaves your machine — a non-negotiable requirement when you are working with SOAP payloads, internal schemas, or regulated data.

XML and JSON share a conceptual model (trees of named nodes containing values) but differ in three important ways that every converter must handle explicitly.

First, XML distinguishes between attributes and child elements. The fragment <user id="42"><name>Ana</name></user> has an attribute id on user and a child element name. JSON has no native concept of attributes. The common convention, popularized by libraries like xmltodict, xml-js, and fast-xml-parser, is to store attributes under a special key — typically @attributes, @_, or a configurable prefix like attr_. This tool uses the @ prefix by default and lets you switch conventions to match your target library.

Second, XML allows mixed content — text and elements at the same level. <p>Hello <b>there</b> friend</p> has three text runs interleaved with a b element. JSON represents this awkwardly through an array of alternating strings and objects, or by concatenating text nodes into a #text key. For most API-style XML (no mixed content), the clean object representation works perfectly; for document-style XML, you may need to preprocess.

Third, XML repetition is implicit. Five identical sibling elements become an array in JSON, but if there is only one element, is it a single object or an array with one item? Most parsers guess based on occurrence count, which breaks downstream code that expects consistent types. The best practice is to consult your XSD or known schema and force array mode for repeated elements — this tool offers an always-array option per path to match that practice.

Namespaces add another wrinkle. <ns:item xmlns:ns="http://example.com"/> can be rendered as ns:item (preserving the prefix), item (dropped), or with the full URI embedded in a metadata key. For interoperability with most downstream JavaScript consumers, dropping the prefix is typical; for SOAP round-trips or XSD validation later, preservation is essential.

Compared to xmltodict (Python), fast-xml-parser (Node), or xml-js, this browser-based converter covers the same core mapping rules without requiring you to install anything or write a single line of setup code. For one-off conversions, interview prep, or exploring an unfamiliar XML feed, the browser tool is the fastest path — paste XML, see JSON, copy, done.

For automation inside an application or data pipeline, you will still want a code library. fast-xml-parser is the fastest pure-JS option, xml-js is the most configurable, and xmltodict is the canonical Python choice. Any of them will match the output of this tool if you set the attribute prefix and always-array options consistently.

Purpose-built XSLT remains the gold standard for complex document transformations — turning one XML schema into another with sophisticated filtering, restructuring, and validation. Use XSLT when you need deterministic, testable, high-volume XML-to-XML transforms. Use this converter when you want JSON out at the end, and you want it in under five seconds.
