XML Formatter and Converter可以处理什么？
XML Formatter and Converter 用于在浏览器中格式化和校验数据，并清楚显示处理结果和限制。 已核对的功能： XML formatting, XML validation, XML minification, XML and JSON conversion.
Formatting preserves meaning better than cross-format conversion
Use Format XML or Minify XML when XML remains the authoritative format. Use XML and JSON conversion for integration work where the chosen attribute and text-node representation is understood and exact lexical preservation is not required.
如何使用？
- Choose Format XML, Minify XML, XML to JSON, or JSON to XML.
- Paste one complete document into Input and select Convert.
- Review the validated output, then copy or download it without uploading the source document.
实际输入输出示例
Format a compact XML document
输入
<project private="true"><name>KitLumi</name><tool>XML</tool></project>输出
<project private="true">
<name>KitLumi</name>
<tool>XML</tool>
</project>The formatter validates the document before rebuilding it with two-space indentation.
常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| The tool reports an invalid closing tag. | An element is missing its closing tag or the tag names do not match exactly. | Balance every start and end tag, including letter case, then run the conversion again. |
| A JSON round trip changes the shape of an element. | XML attributes, text nodes, repeated elements, and namespaces do not map one-to-one to ordinary JSON objects. | Use the generated JSON as an explicit representation and review @_ attribute keys and #text values before relying on a round trip. |
Important behavior of XML Formatter
该工具的实际边界： XML and JSON have different data models, so namespaces, comments, mixed content, and repeated elements may not round-trip exactly.

关于XML Formatter的常见问题
Does the XML Formatter upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the XML Formatter accept?
It accepts one well-formed XML document or a JSON object for JSON to XML mode. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the XML Formatter produce?
It produces formatted or minified XML, or two-space-indented JSON. Copy and download controls appear when the output format supports them.
What limitation should I know?
XML and JSON have different data models, so namespaces, comments, mixed content, and repeated elements may not round-trip exactly.
