Overview
The XML to JSON Converter turns markup-heavy XML — SOAP responses, RSS/Atom feeds, legacy configuration files — into clean JSON your JavaScript or Node.js code can consume directly. It runs on a real XML parser, not regular expressions, so it validates well-formedness, reports the exact line and column of a broken tag, and gives you fine-grained control over how attributes, namespaces, and repeated elements are represented in the resulting JSON.
What This Converter Detects and Handles
- •Real XML validation: malformed XML (unclosed tags, mismatched nesting, bad attribute syntax) is rejected with a precise line and column, not a silent guess
- •Configurable attribute handling: keep attributes prefixed (@_id), convert them into normal object properties, group them under a single $attributes object, or drop them entirely
- •Namespace strategies: keep namespace prefixes on tag names as-is, strip them for cleaner keys, or preserve namespace URIs separately as metadata
- •SOAP cleanup: automatically removes the Envelope/Body wrapper elements common in SOAP responses, leaving just the payload (not round-trip safe once applied)
- •CDATA and type-parsing controls: optionally unwrap CDATA sections into a dedicated property, and choose how aggressively numeric- and boolean-looking text converts to real JSON types
- •Force-array paths: name specific dotted paths, such as rss.channel.item, that should always become a JSON array, even when a feed happens to contain only one item
- •Runs entirely in your browser: your XML data is never uploaded to a server
When You'd Convert XML to JSON
- •Migrating a legacy SOAP API to a JSON-based REST endpoint, so JavaScript or Node.js code can consume the response without a SOAP client
- •Parsing an RSS or Atom feed into JSON to build a content aggregator or news dashboard in a JavaScript framework
- •Converting an XML configuration file, such as a Maven pom.xml or .NET web.config, into JSON for programmatic editing or comparison with other config formats
- •Inspecting a verbose XML API response by converting it to readable, indentation-friendly JSON during debugging
- •Importing an XML data export into a JSON-native database such as MongoDB
How to Convert XML to JSON
- 1.Paste your XML into the input editor, or upload an .xml file
- 2.Pick how attributes should be represented: prefixed properties, plain properties, grouped under $attributes, or ignored entirely
- 3.Choose a namespace strategy — keep, strip, or preserve as metadata — to match how clean you need the resulting keys to be
- 4.Enable SOAP cleanup if you are converting a SOAP envelope and only want the inner payload
- 5.Click Convert, then copy the JSON output or download it as pretty or minified .json
Edge Cases Worth Knowing
- •A single repeated child element (one <item> instead of several) is not automatically treated as an array unless you list its path under Force Array Paths — otherwise it converts to a plain object, which can break code that expects an array
- •Mixed content — an element containing both text and child elements — is flattened, with the text portion exposed as a #text property alongside the child keys
- •Numeric-looking values with a leading zero, such as "00123", or integers beyond safe JSON precision are kept as strings by default; only enable aggressive type parsing if you are certain the data does not include ID-like values
- •XML comments are discarded during conversion, since JSON has no equivalent construct
Limitations
- •Round-trip conversion (XML to JSON and back to XML) is not guaranteed to reproduce the original byte-for-byte — element order, whitespace, and comments are not fully preserved unless Round-Trip Safe mode is enabled, and even that only governs the XML-to-JSON leg
- •Very large XML documents (tens of megabytes) can exceed browser memory or slow down the underlying parser — use a streaming (SAX) parser or a command-line tool such as xmlstarlet for huge files
- •The tool validates well-formedness only, not correctness against an XSD schema — a document that is valid XML but violates a schema will still convert without warning
Need to Go the Other Way?
If you're starting from a JSON object or array and need XML — for example, to call a legacy SOAP endpoint or produce a config file that an XML-only tool expects — use the JSON to XML Converter instead. It lets you control indentation, decide whether @-prefixed keys become attributes, and suppress empty elements.
