XML转JSON

它属于「JSON 工具」分类：JSON 的格式化、结构变换与各种数据格式互转。

• 使用浏览器内置的 <code>DOMParser</code> 解析，遵循标准 XML 规范。
• 元素的<b>属性</b>会转成带前缀的键，例如 <code>id="1"</code> → <code>"@id": "1"</code>。
• 同名的兄弟标签会自动<b>合并为数组</b>，单个则保持对象形式。
• 只有文本内容、没有属性和子元素的节点，会直接简化为字符串。
• 解析失败时会提示具体的错误原因，便于定位标签未闭合等问题。

完全免费、无需注册；所有处理都在浏览器本地完成，文件不会上传到任何服务器。

Parse an XML document into an equivalent JSON object.

Belongs to “JSON Tools”: Format, transform and convert JSON to and from various data formats.

• Parsed with the browser’s built-in <code>DOMParser</code>, following standard XML rules.
• Element <b>attributes</b> become prefixed keys, e.g. <code>id="1"</code> → <code>"@id": "1"</code>.
• Sibling tags with the same name auto-<b>merge into an array</b>; a single one stays an object.
• A node with only text and no attributes or children collapses to a plain string.
• On failure it reports the specific reason, helping locate unclosed tags, etc.

Free, no sign-up; everything runs locally in your browser and files are never uploaded.

1. Open the tool：Open the “XML to JSON” page — no sign-up and nothing to install.
2. Prepare the input：Prepare the content or file to process: paste text or drop a file onto the page (this tool belongs to “JSON Tools”).
3. Provide the input：Paste your content into the input box or drop a file onto the page; you can also click “Sample” to try example data first.
4. Adjust options and run：Adjust the options if needed, then click the process / convert / generate button.
5. Get the result：Everything runs locally in your browser; copy or download the result — your files are never uploaded.

FAQ

Can the attribute prefix change?

Yes — change it to <code>$</code>, <code>_</code> or leave it empty. If empty, an attribute name may collide with and overwrite a child tag.

Why are some nodes strings and others objects?

To keep results compact: a node with neither attributes nor children becomes its text value; once attributes or children exist, an object is required.

Is a single same-named tag also an array?

No. A single occurrence stays an object or string. If your code needs a stable array type, add a guard when reading.

Parse failed — what now?

Usually the XML is invalid — unclosed tags, multiple roots, or an unescaped <code>&amp;</code>. Check the source per the message.
