“Download Your Information

You can download a copy of your Facebook information at any time. You can download a complete copy, or you can select only the types of information and date ranges you want. You can choose to receive your information in an HTML format that is easy to view, or a JSON format, which could allow another service to more easily import it. Downloading your information is a password-protected process that only you will have access to. Once your copy has been created, it will be available for download for a few days. If you’d like to view your information without downloading it, you can Access Your Information at any time.”
