Google Blog Converters 1.0 is an Open Source project that provides the ability to easily migrate blog posts and comments from one blogging platform to another. This initial release provides Python libraries and runnable scripts that convert between the export formats of Blogger, LiveJournal, MovableType, and WordPress.

The code is written in Python with scripts to execute the conversions either on the command-line, through a Windows batch script, or hosted on Google App Engine.

In addition, the source code includes templates for hosting these conversions on Google App Engine. Future additions to the project will include support for BlogML and synchronization tools between various services that do not provide a import/export feature but do provide APIs for accessing and modifying blog contents.

See the following websites to view examples of these converters hosted on Google App Engine.
