From the project : menu, use the export option to export details of your project.

Export tasks

You can choose to export the whole project, one branch of your work breakdown structure, or a single task.

You can export the tasks in CSV or Excel format for loading into a spreadsheet program.

You can also export tasks in JSON format, which provides some more features if you import the tasks again.

When you export the tasks you can select whether to only export details that would be imported. Select this to get a small export that is easier to change and use with import. Do not select this option to get a report view for the tasks because it does not contain status information.
