Frequently Asked Questions
How to convert JSON to XML?
Paste your JSON data or upload a .json file into the input area above, then click Convert. The tool wraps your JSON data in a <root> element and converts each key to an XML tag, each value to text content. Download the .xml file or copy the output directly. All processing is client-side — your data never leaves your device.
How to convert XML to JSON?
Use the XML to JSON converter on this site. Paste your XML or upload an .xml file, click Convert, and get a clean JSON representation. The parser handles attributes (prefixed with @_), nested elements, and repeated elements (converted to arrays).
When to use JSON vs XML?
Use JSON for: REST APIs, web applications, configuration files, and real-time data exchange. JSON is lighter, faster to parse, and maps naturally to JavaScript objects. Use XML for: SOAP web services, document markup (like HTML/SVG), enterprise systems with strict schemas (XSD validation), and scenarios requiring metadata/attributes on elements. JSON is generally preferred for new projects due to its simplicity and smaller payload size.
When to use XML over JSON?
Choose XML when you need: schema validation (XSD for strict data contracts), namespaces to avoid element name collisions, complex document structures with mixed content (text + child elements), XSLT transformations, or SOAP-based services. Also prefer XML in regulated industries (finance, healthcare) where established XML standards exist (XBRL, HL7, FpML).
How does the readability of JSON compare to XML?
JSON is generally more readable for data exchange because it uses fewer characters and maps directly to common data structures (objects, arrays). A JSON object {"name":"John"} is shorter than its XML equivalent <person><name>John</name></person>. XML's closing tags and attributes add verbosity but improve self-documentation. For configuration files, JSON and YAML have largely replaced XML due to better readability.
How to convert XML to JSON in JavaScript?
Use the fast-xml-parser library: import { XMLParser } from 'fast-xml-parser';
const parser = new XMLParser({ ignoreAttributes: false });
const json = parser.parse(xmlString);
You can also use the browser's built-in DOMParser: const dom = new DOMParser().parseFromString(xml, 'text/xml');
// then traverse the DOM tree and build a JSON object
How to convert JSON to XML in REST API?
Configure your API framework to support both formats through content negotiation. In Express.js, use middleware that checks the Accept header: if application/xml, convert the JSON response to XML using fast-xml-parser's XMLBuilder. In Spring Boot, add jackson-dataformat-xml dependency and annotate controllers with @RequestMapping(produces = {"application/json", "application/xml"}).
