Here are some examples of how to format your .csv files:

• Name
  • Friendly name to appear in the Portal to reference
• Website
  • Must be a valid domain - full URLs and IPs are ignored
• Mode 
  • Refers to including or excluding subdomains - True = include, False = exclude subdomains.
• Rule
  • Filtering decision to allow or block the website
• Inherited from Global
  • Ignored on imported, but if you took an Export to make changes, it will be included in the file
