Select Addressbook from menu bar at bottom of page.
Clean up your addressbook before continuing. Remove bad addresses and duplicates. Correct labeling, etc.
Select Import/Export from menu bar at top of Addressbook page.
Export your address book to your local machine (desktop) twice, once as a comma-separated file (.csv) and once as a tab-separated file (.tsv). The names of the resulting files will be turba.csv and turba.tsv. Export in both formats in case the comma-separated format doesn't work well with your data, e.g., you have commas within the data itself which causes problems.
