The use of NodeXL Pro Facebook data importers requires a Facebook account.
If you are the Admin of a Facebook Fan Page, you can analyze all comments, likes and shares based on individual users. If you are not the Admin of a Fan Page you need to use the Facebook Fan Page Importer, but then the user data is annonymized, which will result in a scattered network.
With the Facebook Fan Page Importer you can also download posts, comments and replies to create Post-Comment-Like network treemaps. You can get as much content from fan pages as you like, yet the data download may take quite a while as the download stops and resumes.
The Facebook Fan Pages Importer allows you to explore Page-likes-Page networks up to a 3.0 network for one Fan Page or a list of Fan Pages.
Please note that the download of network data from large fan pages can easily max out your system memory if you do not limit the number of reactions, likes and shares when setting up the data importer.
NOTE: Currently, the Facebook Group Network Importer is not working.
