UPDATE: beware, Yahoo Pipes has now been shutdown by Yahoo! and the Google Feed API has been deprecated. Check superfeedr.com's API which also does RSS to JSON conversion.

You can use google feed api service

Example:

https://ajax.googleapis.com/ajax/services/feed/load?v=2.0&q=http://phys.org/rss-feed/&num=20

Structure https://ajax.googleapis.com/ajax/services/feed/load?v=2.0&q=RSS_URL_TO_CONVERT&num=

Also if you want better control on RSS conversion use http://pipes.yahoo.com/pipes/ where you can visualize data flow.

EDIT: As yahoo pipes is no more working, here are the list of alternatives http://www.makeuseof.com/tag/12-best-yahoo-pipes-alternatives-look/

RSS is already in XML format, which is natively parsable by all browsers. I would recommend just parsing the XML directly instead of converting to json for parsing.

    Web browsers wont let you download xml, they check the mime type, in a browser without lots of issues, otherwise I would agree. – Ed_ May 18 '11 at 19:13

  • for example, i tried this - http://ejohn.org/apps/rss2json/?url=http://sfbay.craigslist.org/search/apa/pen?query=&minAsk=1500&maxAsk=2000&bedrooms=2&neighborhood=&format=rss and i didn't get any result –  Mar 22 '09 at 06:25
  • You downloaded the Perl scripts and followed all those directions? – BobbyShaftoe Mar 22 '09 at 18:50

I'd recommend using Yahoo Pipes to do this. You can simply pull the feed, and it acts as a proxy; JSONP is supported as well.

You can also try the Oxygen XML Editor (http://www.oxygenxml.com/). They offer a 30-day trial version and it's cross-platform. You can find the converter under Tools -> XML to JSON...

You could try using one of the many javascript libraries to navigate through the XML.

For example, here. There are many more libraries, here are the ones Google thought were good enough to host.
