Trim Down Your RSS Reading List by Removing Duplicate Feeds
If you are following the RSS feed for a long time, then there may be duplicate feeds present in your news aggregator, which are separate URLs, but talk on the same subject on the web.
If you are following the RSS feed for a long time, then there may be duplicate feeds in your news aggregator, which are separate URLs, but point to the same content on the web.
This can be due to various reasons like:
The website xyz.com was originally a feed on xyz.com/feed but later moved to xyz.com/rss without redirecting the previous one. You can subscribe for both feeds.
Your news reader is not smart enough to identify duplicate feeds and does not provide any warning when you try to add a feed already in your Subscription List.
How to Detect and Remove Duplicate RSS Feeds?
For any reason, removing duplicate RSS feeds from your membership is relatively easy.
The first step is to export your entire feed subscription list as an OPML file.

The next step is to sort the contents of this file.
You can use the Sort command in DOS / UNIX or simply import this OPML file into Google Docs / Microsoft Excel and use the built-in sort feature.
If your reading list is small, then scroll through the list to find any duplicate subscriptions – if two or more feeds share the same value in the text, title and html URL field, it means that they are duplicate.
Make a note of those feeds in your RSS reader and unsubscribe from them.
