Is my data sent to a server?

No. All conversion runs 100% in your browser. Your XML and JSON data never leaves your device.

What is the main challenge of converting XML to JSON?

XML has features with no direct JSON equivalent: attributes vs. elements, mixed content (text + child elements), namespaces, processing instructions, and comments. The converter makes opinionated choices about how to represent these — configurable via options.

How are XML attributes handled in the JSON output?

By default, attributes are represented as properties prefixed with "@" (e.g. @id, @class). This is the most common convention and is compatible with libraries like fast-xml-parser and xml2js. You can configure the prefix or merge attributes with element content.

Can I convert SOAP XML responses to JSON?

Yes. Paste the SOAP envelope XML and the tool converts it to JSON. The SOAP namespace prefixes are preserved in the output. This is useful for working with legacy Salesforce SOAP API responses.

What is the difference between XML and JSON for data exchange?

JSON is lighter, easier to parse in JavaScript, and the default for modern REST APIs. XML supports schemas (XSD), namespaces, and mixed content — making it more expressive but more complex. Legacy enterprise systems (SOAP, EDI, Salesforce Metadata API) use XML; modern APIs use JSON.

About the XML / JSON Converter

XML and JSON are the two dominant data interchange formats in enterprise software. Modern REST APIs use JSON; legacy systems, SOAP services, and the Salesforce Metadata API use XML. Converting between them is a frequent task when integrating systems or migrating data. This tool handles bidirectional conversion with configurable options for attribute handling, namespaces, and array detection.

What this tool converts

XML → JSON

Converts XML elements, attributes, and text content to JSON. Configurable attribute prefix, array detection, and namespace handling.

JSON → XML

Converts JSON objects to XML elements. Configurable root element name, attribute prefix, and indentation.

SOAP Support

Handles SOAP envelopes with namespace prefixes — useful for working with legacy Salesforce SOAP API and enterprise web services.

Validation

Validates XML well-formedness and JSON syntax before conversion — shows the exact line and character of any parse error.

Pipeline

JSON Formatter — format and validate the JSON output.
JSON to TypeScript — generate TypeScript types from the converted JSON.
Text Diff — compare two XML or JSON documents.
