RSS vs JSON: Format Comparison

Key differences between the two formats

Feature	RSS	JSON
Syntax	XML with <channel>, <item>, <title>, <link>	Nested objects with arrays of items
Tooling	Read by RSS readers and aggregators	Read by every web frontend, every script, every AI pipeline
Schema	RSS 0.9 / 2.0 plus extensions like Media RSS, iTunes	Flexible — keys mirror the RSS structure
File size	Slightly larger due to XML overhead	Slightly smaller, especially with minimal whitespace
Comments	XML <!-- comments --> allowed	No comment support
Best for	Publishing for feed readers	Programmatic ingest, AI agents, modern UIs

When to Convert

Common scenarios where this conversion is useful

Power dashboards and frontends

Modern frontends and component libraries consume JSON natively. Convert an RSS feed once at the edge so the browser doesn't have to parse XML.

Ingest feeds into LLM pipelines

Most AI agents and prompt pipelines work with JSON. Convert RSS feeds to JSON before passing to a summarizer or RAG system.

Build custom aggregators

Pull a dozen RSS feeds, convert each to JSON, then merge and sort programmatically with familiar JSON tools (jq, Lodash, custom scripts).

Archive feeds to NoSQL databases

Document stores like MongoDB, DynamoDB, and Firestore accept JSON natively. Convert RSS once and write directly without an XML adapter.

Who Uses This Conversion

Tailored guidance for different workflows

Developers

Convert RSS config files to JSON for compatibility with different tools or frameworks
Transform RSS API responses to JSON for debugging, logging, or documentation

Validate the converted JSON output with a linter to catch any structural issues from the conversion

Watch for data type coercion (e.g., numbers becoming strings) when converting between RSS and JSON

Data Analysts

Convert RSS exports to JSON for importing into spreadsheet software, databases, or BI tools
Transform RSS datasets to JSON for sharing with teammates who use different analysis tools

Check that column delimiters and quote escaping are handled correctly in the converted JSON file

Preview the first few rows of the JSON output to verify headers and data alignment

System Administrators

Convert RSS configuration to JSON when migrating between infrastructure tools or platforms
Transform RSS log exports to JSON for ingesting into monitoring or analysis systems

Back up the original RSS config before converting, especially for production systems

Test the converted JSON in a staging environment before deploying to production

How to Convert RSS to JSON

1

Upload your RSS file

Drag and drop your RSS file onto the converter, or click browse. The file is uploaded over an encrypted connection.

  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@input.rss" \
  -F "target=json" \
  -o output.json --fail

const form = new FormData();
form.append('file', fileInput.files[0]);
form.append('target', 'json');

const res = await fetch('https://changethisfile.com/v1/convert', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer YOUR_API_KEY' },
  body: form
});
const blob = await res.blob(); // your converted JSON file

Frequently Asked Questions

What RSS versions does this support?

RSS 2.0 and 0.9x. Atom 1.0 feeds will also parse since the converter handles generic XML feed structures, though field names differ.

Are item enclosures preserved?

Yes — podcast and media enclosures (audio/video URLs, sizes, types) are preserved as JSON objects under the items array.

What about Media RSS extensions?

Media RSS namespaces (media:thumbnail, media:content) are preserved with the namespace prefix in the JSON keys.

Are pubDates parsed into ISO format?

No, pubDate values are kept as the original RFC 822 strings to preserve fidelity. Convert to ISO 8601 in your application code if needed.

Does this work for podcast feeds?

Yes. iTunes podcast namespaces (itunes:author, itunes:category, itunes:duration) are preserved with prefixed keys.

Can I convert remote feeds via URL?

Not directly — upload the RSS file. Use curl to download a feed first, then upload the saved file.

Is my feed uploaded somewhere?

It is uploaded to our backend over HTTPS, parsed, and immediately deleted. We do not log feed contents or URLs.

Are HTML descriptions in items preserved?

Yes. HTML inside <description> or <content:encoded> is preserved as a string in the JSON output.

What's the file size limit?

Up to 50MB. Even very long RSS feeds with thousands of items typically fit well under this limit.
