By default the Export CSV file delimiter is a comma. Some countries like the Netherlands and other European countries use Semi Colon's or Tabs as the default standard for CSV files. Microsoft Sets this default in the operating system (found in Regional and Langauge Options in the Regional Options tab).
This setting can be customized for your BuzzStream account by the account owner.
