iGoogle lets you export your setting and gadgets as an XML file, which can be easily processed and transformed into an OPML file. Here's what you’re required to do to export your your iGoogle feed to OPML:
- Log in to a Google account.
- 2. Open this page, right-click and view page source. Copy the entire content of the file to the clipboard (Ctrl+A, Ctrl+C).
- Paste the code below and then click on “Convert to OPML”. (If you are concerned about sharing private data, you should know that this is just a client-side script that doesn't store your data and it doesn't send it to a third-party service.)
- Save the output in a XML file: igoogle-subscriptions.xml.
To import the file in Google Reader, go to Settings, click on Import/Export and upload the OPML file. In Netvibes, the steps are less obvious: Add content –> Add a feed –> Import. Most feed readers have an option to import a list of subscriptions.
