If you have a blogspot blog or custom domain, there is a Blogger
import in wordpress:

• wp-admin
• Left Sidebar Tools, Import
• Select Blogger

Of course, if you have your own hosting and use Blogger via FTP to
publish your blog, this is not an option

I tried using the RSS feed import in blogger (as did other people), but when I tried the import, it failed with no errors.  (No posts were added to my WordPress blog, yet the import displayed only, “All done, Have fun!”

Instead, I chose to convert my Blogger FTP blog to blogspot.

• Go to Blogger.com
• Click on “Settings” for your ftp blog.
• Under the “Settings” tab, click “publishing”

You’ll see the following options

Switch to: • blogspot.com (Blogger’s free hosting service) • Custom Domain (Point your own registered domain name to your blog) • SFTP (secure publishing on your ISP server)

• Click blogspot.com
• Pick an arbitrary blogspot.com address, verify the word, and select [Save Settings].

Then follow the normal steps to import the redirected blog into WordPress.

If you’ve already imported from Blogger, you may have to select [Clear Account Information] and then [Authorize] to refresh the list of blogs.
