XML to JSON Converter
Convert XML data to clean JSON format
Use XML to JSON Converter
Convert XML to JSON
Paste XML from a feed, SOAP response, or config file and inspect the JSON mapping before using it in code.
Assumptions
Use XML to JSON Converter for data and measurement conversion work when you need a local browser check and output you can review before using it in the next step.
Worked example
When To Use XML to JSON Converter
- Paste a real example into XML to JSON Converter that includes the edge case you need to check.
- Review whether the output matches the converted value, table, or format against the source input before using it in the next step.
Sample Input And Output Checks
- Start with a sample that includes the failure you are trying to reproduce, not only a clean placeholder.
- Review numeric precision, unit assumptions, delimiter handling, and destination format before trusting the output.
- Run one known sample through the converted output before relying on it in the next step.
About This Tool
XML to JSON Example
Use this converter to inspect XML responses, RSS items, SOAP payload fragments, or configuration documents as JSON.
<order id="A-1007"><total currency="USD">49.95</total></order>
A JSON object that exposes attributes with a prefix convention and keeps element text visible for review.
- Pasting malformed XML with multiple root nodes or mismatched closing tags.
- Expecting attributes, namespaces, and mixed content to map the same way in every library.
- Treating JSON output as a schema contract before checking repeated elements and arrays.
- Use XML Formatter first when the source is dense or hard to inspect.
- Use JSON Path Finder to locate converted fields.
- Use JSON to YAML or JSON Formatter if the output moves into config or review docs.
Local processing note: XML parsing happens locally. Legacy XML often contains customer, shipment, invoice, or auth data that should be redacted.
XML to JSON Conversion: Modernizing Data for the JavaScript Era
The XML to JSON converter transforms XML (eXtensible Markup Language) documents into readable JSON (JavaScript Object Notation) in your browser. XML has served as the dominant data interchange format for over two decades, underpinning SOAP web services, enterprise service buses, government data standards, and document-centric workflows across many industries. However, the modern software landscape has shifted decisively toward JSON. REST APIs return JSON by default, JavaScript and TypeScript applications parse JSON natively with a single call to JSON.parse(), NoSQL databases like MongoDB and CouchDB store JSON documents, and front-end frameworks including React, Vue, and Angular consume JSON data through fetch and axios. This shift creates a persistent need to convert legacy XML data into JSON for consumption by modern systems. For the reverse transformation, use our JSON to XML Converter to generate well-formed XML from any JSON input.
Technical Deep Dive: XML Features and Mapping Strategies
XML possesses several features that have no direct equivalent in JSON. This converter adopts the widely used @-prefix convention for attributes, maps text-only elements to direct string values, and uses "#text" for mixed content. Namespace prefixes are preserved in element names. CDATA content is treated identically to regular text nodes. Comments and processing instructions are discarded during parsing. For converting the resulting JSON to other formats, try our JSON to YAML Converter or our YAML to JSON Converter for the reverse direction.
Real-World Use Cases for XML to JSON Conversion
XML-to-JSON conversion is a daily requirement across numerous professional domains including legacy API modernization, SOAP to REST migration, RSS and Atom feed parsing, XML configuration migration, and data lake ingestion pipelines. This tool lets developers prototype the expected JSON structure before implementing gateway transformation policies. For exploring and validating the converted JSON, visit our All-in-One JSON Tools suite.
Comparison with Libraries and Best Practices
Popular libraries for programmatic XML-to-JSON conversion include xml2js and fast-xml-parser for Node.js, xmltodict for Python, XSLT 3.0 with fn:xml-to-json, and Jackson XML for Java. Best practices include testing with representative real-world XML documents, deciding on an attribute convention before writing code, handling repeated elements explicitly, and validating output JSON against a schema. For formatting your code output, our JSON Formatter handles XML, JSON, and many other languages, and for escaping special characters, use our XML Escape/Unescape tool.
What Changes During XML to JSON Mapping
XML contains concepts that JSON does not model directly, so every converter has to make interpretation choices. Attributes may become keys with prefixes, repeated sibling elements may become arrays, text-only nodes may collapse to strings, and mixed content can require special marker fields. That means the output JSON can parse correctly yet still differ from what another library would produce. Before you wire converted output into code, verify the chosen attribute and array strategy against the structure your application actually expects.
Best Use Cases for Browser-Side XML to JSON Conversion
This page is most helpful when you need to inspect legacy XML quickly, prototype a SOAP-to-REST bridge, review RSS or Atom data, or prepare configuration documents for JavaScript tooling. Because conversion happens in the browser, it is also a safer option for internal payloads that you do not want to upload to a third-party service. Once you have the JSON shape, continue with our JSON Path Finder or JSON Sorter to inspect and normalize the result.
