Frequently Asked Questions

What feed formats does the RSS Viewer support?
It parses RSS 2.0 and Atom feeds. Paste the feed XML or upload a file, and the tool detects the format and renders a readable preview of the channel and its items.
What is the difference between RSS and Atom?
RSS and Atom are both XML-based syndication formats. RSS 2.0 uses channel and item elements defined by the RSS Advisory Board, while Atom is an IETF standard (RFC 4287) using feed and entry elements with stricter date and identifier rules. This viewer reads both.
Is my feed data sent to a server?
No. The viewer validates and parses feed XML entirely in your browser using built-in parsing APIs. Your feed content never leaves your device.
Why does my feed show an invalid or parse error?
Errors usually mean the XML is malformed—unclosed tags, missing required RSS or Atom elements, or stray characters. Run the feed through the W3C Feed Validation Service to pinpoint the issue, then paste the corrected XML.
Can I view the parsed feed as JSON?
Yes. Switch to JSON Mode to see the feed represented as a structured JSON object, which makes it easy to inspect how each element and attribute is mapped.
