Detection rulesAccepts a JSON Feed (version + items) or a plain array of objects; title / link / summary / date are auto-detected from common field names (title, url, summary, date and friends), and XML special characters are escaped.

Why use JSON to RSS

RSS 2.0 and Atom

Turn the same data into RSS 2.0 or Atom in one click, ready for readers, aggregators or podcast platforms.

Auto field detection

Title / link / summary / date are detected from common field-name families — no need to reshape your data first.

Valid XML output

All special characters are escaped and dates follow RFC 822 / ISO 8601, so validators pass out of the box.

JSON Feed compatible

Paste a jsonfeed.org-style JSON Feed and the channel metadata reuses its own title / home_page_url.

Local · no upload

Generation runs entirely in your browser; data is never uploaded or stored.
