XML を JSON に変換する方法（オンライン）

  1. ステップ 1 – XML を貼り付け/アップロード

    左のエディタに XML を貼り付けるか、.xml ファイルをアップロードします。

  2. ステップ 2 – 構造を確認する

    編集に合わせて XML が解析され、要素・属性・入れ子ノードを反映した JSON オブジェクトツリーに変換されます。

  3. ステップ 3 – JSON 出力を確認

    右側に整形された JSON が表示されます。XML のエラーはエディタ上部に表示されます。

  4. ステップ 4 – JSON をコピー/ダウンロード

    変換した JSON をコピーするか、.json としてダウンロードして API、テスト、アプリで使えます。

Quick tips for XML to JSON

  • Well-formed XML is required; unclosed tags or invalid characters will cause parse errors.
  • Attributes are usually mapped with a prefix (like @), and text nodes with #text.
  • After converting, you can generate JSON Schema or TypeScript types for the resulting JSON structure.
Example: XML to JSON
<!-- XML input -->
<order id="ORD-1001">
  <customer name="Maeve" email="[email protected]" />
  <item sku="SKU-001">Wireless Mouse</item>
  <item sku="SKU-002">Mechanical Keyboard</item>
</order>

// JSON output (simplified)
{
  "order": {
    "@id": "ORD-1001",
    "customer": {
      "@name": "Maeve",
      "@email": "[email protected]"
    },
    "item": [
      { "@sku": "SKU-001", "#text": "Wireless Mouse" },
      { "@sku": "SKU-002", "#text": "Mechanical Keyboard" }
    ]
  }
}

よくある質問

What XML features are supported in the conversion?

The converter supports standard XML elements, attributes, text content, and CDATA sections. It handles nested structures and converts them to appropriate JSON objects and arrays.

How are XML attributes handled in the JSON output?

XML attributes are typically converted to JSON properties with a special prefix (like '@') to distinguish them from element content, or they may be merged into the element's JSON representation depending on the conversion logic.

Can I convert large XML files?

Yes, the converter can handle large XML files, but performance may vary based on file size and complexity. For very large files, consider breaking them into smaller chunks if possible.

What happens to XML namespaces during conversion?

XML namespaces are preserved in the JSON output, typically as part of the element names or as separate properties. The exact handling depends on the conversion implementation.
