RSS and Atom to JSON Converter は何をしますか？
RSS and Atom to JSON Converter はブラウザ上でデータやファイルを変換するツールで、結果と制限を明確に示します。 検証済みの機能： RSS XML parsing, Atom XML parsing, Attribute preservation, Formatted JSON output.
Preserve first, normalize deliberately
Use the structural JSON for inspection and loss-conscious processing. Add a documented normalization layer only when downstream code requires one feed model.
使い方
- Paste a complete RSS or Atom XML document.
- Choose Convert to parse it locally.
- Inspect, copy, or download the JSON tree.
実際の入出力例
Parse a minimal RSS channel
入力
<?xml version="1.0"?><rss version="2.0"><channel><title>News</title></channel></rss>出力
{
"rss": {
"channel": { "title": "News" },
"@_version": "2.0"
}
}Elements become object properties and XML attributes use an explicit attribute prefix.
一般的なエラーと対処
| 症状 | 原因 | 対処 |
|---|---|---|
| The tool reports malformed XML. | A tag is unclosed, mismatched, or contains an invalid character. | Validate and repair the XML before feed conversion. |
| Two feeds produce different JSON shapes. | RSS and Atom use different element vocabularies and nesting. | Normalize fields in application code only after detecting the feed dialect. |
Important behavior of RSS → JSON
このツール固有の制限： The output mirrors XML structure rather than forcing every feed dialect into one lossy normalized schema.
標準と実装の参考資料
- RSS 2.0 specification (opens in a new tab)Defines RSS channel and item elements.
- RFC 4287 — Atom (opens in a new tab)Defines the Atom syndication format.
RSS → JSON — FAQ
Does the RSS → JSON 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 RSS → JSON accept?
It accepts well-formed RSS 2.0, RSS 1.0, or Atom XML. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the RSS → JSON produce?
It produces formatted JSON preserving parsed feed elements and attributes. Copy and download controls appear when the output format supports them.
What limitation should I know?
The output mirrors XML structure rather than forcing every feed dialect into one lossy normalized schema.
