XML to JSON Converter

XML (Extensible Markup Language) and JSON (JavaScript Object Notation) are both structured data formats, but they have significant differences in design philosophy:

Selection suggestions: If you need complex file structure, Namespace, Attribute relay data → choose XML; Web API, front-end and back-end communication, lightweight data exchange → choose JSON. Many modern APIs internally convert to JSON processing after receiving XML.

SOAP(Simple Object Access Protocol) is a rigorous XML-based communication protocol proposed by Microsoft in 1998. SOAP messages must use XML format and follow strict structural specifications (Envelope → Header → Body).

REST(Representational State Transfer) is a lightweight API design style proposed by Roy Fielding in 2000. REST APIs typically use JSON, but XML formats are also supported.

During the modernization process, many enterprises will convert SOAP/XML Legacy API to REST/JSON architecture. This tool is designed for this conversion scenario.

Sitemap XML(Sitemap) is an XML file that tells search engines which pages are on your site, how often they are updated, and their relative importance. The standard format is defined by sitemaps.org.

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/</loc>
    <lastmod>2024-01-15</lastmod>
    <changefreq>daily</changefreq>
    <priority>1.0</priority>
  </url>
</urlset>

Sitemap XML is critical for SEO because:

• Help search engines discover new pages and updated content faster
• Ensure all pages of a large website are indexed
• Provide relay information (last update time, change frequency)
• Supports special content types such as pictures, videos, news, etc.

The Sitemap XML for this site is located at:/sitemap.xml

RSS(Really Simple Syndication) is an XML-based content subscription format for publishing frequently updated content (such as blog posts, news, podcasts). An RSS feed is essentially an XML file.

<?xml version="1.0" encoding="UTF-8"?> <rss version="2.0"> <channel> <title>ToolHub Blog</title> <link>https://toolhub.example.com/</link> <item> <title>JSON vs XML Comprehensive Comparison</title> <pubDate>Mon, 15 Jan 2024 10:00:00 GMT</pubDate> </item> </channel> </rss>

Main uses of RSS feeds:

• Allow users to subscribe to the latest content from blogs and news websites
• Podcast publishing and distribution (Apple Podcasts, Spotify and other platforms use RSS)
• Content aggregation and automated workflows
• Social media scheduling and content republishing

When converting XML to JSON, the processing of Attribute and Text nodes is the most critical design decision. This tool provides three options:

• @ prefix (recommended to enable): Change the XML Attribute to @ Key representation of the prefix. For example <book category="fiction"> → "@category": "fiction". This approach clearly distinguishes attributes from child elements.
• #text node: When an element has both Attribute and text content, the text content will be placed #text key. For example <title lang="en">Hello</title> → {"@lang": "en", "#text": "Hello"}。
• Reserve Attribute: When this option is turned off, all attributes are ignored and only the element content is preserved. Suitable for scenarios where only text content is required.

XML: <book id="b1" lang="en">The Hobbit</book> ✅ @prefix + #text: {"@id": "b1", "@lang": "en", "#text": "The Hobbit"} ❌ None Attribute: "The Hobbit"

100% safe. This tool adopts a pure front-end (Client-side) architecture, and all XML parsing and JSON conversion are completed in your browser.No data will be uploaded to any server。

This means:

• Your API specifications, sitemap data, and RSS feed configurations never leave your computer
• No internet connection is required to perform the conversion (except when loading the page for the first time)
• No backend servers store or process your content
• Even ToolHub administrators cannot access the data you enter

Whether it's SOAP API XML requests, Sitemap settings or Legacy system data, it's all handled safely here.

When converting XML to JSON, the conversion results may need to be adjusted due to the structural differences between the two formats. The following are common structural changes and processing methods:

• Repeated elements are automatically transformed into an array: Repeated child elements with the same name in XML (such as multiple <item>) will be converted to a JSON array.
• Attribute stands alone as an attribute: When the @ prefix is enabled, the Attribute becomes an independent JSON Key and will not be confused with child elements.
• Empty element handling: Empty XML element (<element></element>) may be converted to Null or an empty string, depending on the settings.
• Mixed content: When an element contains both text and child elements, the text will be placed #text key.

Recommendation: Check the JSON structure against the original XML after conversion, paying special attention to whether arrays and nested objects are correct. You can use Tree View mode to intuitively inspect the JSON structure.
