You can easily download family and member data into a csv or Excel file.  Navigate to either the Family Search or the Member Search screen and use the search criteria to get the data you want to download visible on the form (for all Active families or members press the Reset link) then press the Download link and select csv or xlsx from the drop down field and give the file a name and voila!  You have all the columns in the families or members table.  This will come in handy when you might be doing a survey and need to upload emails to Survey Monkey or perhaps an outside mailing or even to send data to your budget company to give them an update of active families.
