To import an OPML file into Feedly:
Make sure you’re logged in to your Feedly account (on desktop), and then go to https://feedly.com/i/cortex.
Click on the Choose OPML file button or drag and drop the OPML file to upload.
We’ll automatically add your sources and feeds to your Feedly
You should see all your feeds in your Feedly account.
Note: This won’t remove any of the feeds you already have in your account — it will just add additional sources and feeds. Also, the OPML import will only import your feeds and won’t be importing any boards or read later articles.
