We're happy to announce a new open source application that allows you to import and export your Google Tasks, called Google Tasks Porter.
Google Tasks Porter is designed with other applications that contain task lists in mind. It supports import and export via the iCalendar format which is used by a variety of applications, including iCalendar itself. It also supports import and export to Microsoft Outlook via a CSV format. Additionally, Google Tasks Porter supports export from Remember the Milk using its iCalendar export, and import to Remember the Milk via email. You can also download a list of all your tasks in an HTML format which is designed to be portable and parseable.
Google Tasks Porter allows you to create a set of "snapshots" of your data, each representing a list of all your tasks at a particular point in time. You can then save or delete these snapshots, and you can export a snapshot at any time to another application using any of the available formats. You can also upload an ics or csv file in order to import the tasks contained therein into Google Tasks.
The application is available on the web at http://google-tasks-porter.appspot.com. The source code is also available on Google Code at http://google-tasks-porter.googlecode.com using the Apache License, Version 2.0. Please try the application out and let us know what you think. You can provide feedback via the mailing list at firstname.lastname@example.org.
