Blog authors around the world, Google would like to remind you that it’s your blog, your data. Now that Blogger allows users the ability to export all contents of their blog, the Data Liberation team would like to announce the Google Blog Converters project. This new Open Source project provides the ability to easily move blog posts and comments from service to service. This initial release provides Python libraries and runnable scripts that convert between the export formats of Blogger, LiveJournal, MovableType, and WordPress.

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.

We’re excited to provide this level of control for your personal blog data. Contributions to the project are always welcomed and encouraged, so check out our source code (download, 2.7 MB zipped) and let us know what you think. We look forward to your feedback in our discussion group.
