How do I convert XML to JSON?

Paste your XML content into the input box and click Convert. The tool transforms XML elements into JSON objects, attributes into @-prefixed keys, and text content into #text values.

How are XML attributes handled?

XML attributes are converted to JSON keys prefixed with @ (e.g. @id, @class). You can customize this prefix in the options.

Yes. All parsing runs 100% in your browser using the built-in DOMParser API. No data is sent to any server.

How to Convert XML to JSON Online

XML (Extensible Markup Language) was the standard for configuration files and enterprise API feeds for decades, but it is heavily verbose and challenging to read or digest in modern web environments. JSON (JavaScript Object Notation) has replaced XML as the industry default for APIs due to its light weight and native compatibility with JavaScript. This converter parses your complex XML files and outputs clean, structured JSON structures instantly.

Step-by-Step Conversion Guide

Paste XML Input: Copy and paste your XML snippet or full document into the "XML Input" block above.
Adjust Settings:
- Indent: Select 2 spaces, 4 spaces, or minified JSON layout.
- Attr Prefix: Choose a prefix character (like @ or _) to differentiate XML attributes from child elements.
- Trim Text: Check this to strip leading/trailing whitespace from XML text nodes.
Trigger Conversion: Click the blue "Convert to JSON" button.
Copy or Download: Copy the JSON to your clipboard or download it as a .json file.

XML vs JSON: A Structural Comparison

Because XML and JSON represent data differently, elements are mapped using industry-standard conversion rules to ensure structural integrity and prevent data loss:

XML Tags to JSON Keys: Every XML tag (e.g. <user>) is mapped to a JSON key name.
Attributes Mapping: Attributes inside elements (like <user id="12">) are converted into properties prefixed with your selected character (e.g. "@id": "12").
Text Content: For basic elements with only text content (e.g. <title>Hello</title>), it translates directly to a key-value string: "title": "Hello". If the tag has attributes and text, it is structured as {"title": {"@lang": "en", "#text": "Hello"}}.
Repeated Elements to Arrays: Multiple tags with the same name under the same parent element are automatically grouped into a single JSON array list.

Frequently Asked Questions

What is a parser error in XML?

XML has very strict syntax rules. Unlike HTML, XML will fail to parse if tags are not closed correctly, if attribute values are not wrapped in quotes, or if special characters (like &, <, or >) are not escaped as HTML entities (e.g. &). If you see a parser error, check that your XML is well-formed.

Does this tool support XML Namespaces?

Yes. Because our tool uses your browser's native XML parser engine, it parses namespaces (e.g. <ns:tag>) and retains the full qualified tag name prefix inside the resulting JSON object keys, so no namespace metadata is lost.

How does CDATA handling work?

CDATA (Character Data) blocks are used in XML to wrap raw text containing character blocks (like HTML markup or code) that shouldn't be parsed as XML. The converter automatically extracts the text payload within CDATA blocks and maps it to standard JSON string values.

Is my XML content safe?

Yes. The parsing runs 100% locally in your browser using the built-in DOMParser Web API. Your XML files, logs, or corporate datasets are never uploaded to any external server, guaranteeing total privacy and security.
