WordPress provides facility to import your posts and comments from your TypePad blog to self hosted WordPress blog. To import your posts and comments, first you will need to export your TypePad blog’s posts and comments in the Movable Type Import Format. To create an export file, go to Blogs > Settings > Import/Export and scroll down to the Export section. Click the Export button to generate the export file. Once the export is complete, you will see a download link. If you are on Windows, click on the link with the right mouse button and choose Save Target As or Save Link As to save the export file to your computer. If you are on a Mac, hold down the Option key while clicking and choose the Save Link As menu option.
Once you export your TypePad posts and comments,
 Login to your WordPress blog admin panel.
 Go to Tools -> Import.
 Click on “Movable Type and TypePad” and follow the on screen instructions.
