What does the RSS and Atom Feed to JSON Converter do?
Use this tool when you need a browser utility that parses RSS or Atom XML and exposes its complete local parse tree as JSON. It accepts well-formed RSS 2.0, RSS 1.0, or Atom XML and returns formatted JSON preserving parsed feed elements and attributes. Results are deterministic for the same input except where cryptographic randomness, current time, or a live provider response is part of the task.
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.
How do you use it?
- Paste a complete RSS or Atom XML document.
- Choose Convert to parse it locally.
- Inspect, copy, or download the JSON tree.
Worked example
Parse a minimal RSS channel
Input
<?xml version="1.0"?><rss version="2.0"><channel><title>News</title></channel></rss>Output
{
"rss": {
"channel": { "title": "News" },
"@_version": "2.0"
}
}Elements become object properties and XML attributes use an explicit attribute prefix.
Common errors and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| 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
The output mirrors XML structure rather than forcing every feed dialect into one lossy normalized schema.

Frequently asked questions about RSS → JSON
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.
What changed?
Added RSS XML parsing, Atom XML parsing, Attribute preservation, Formatted JSON output, responsive controls, explicit runtime disclosure, and task-specific examples and limitations.
