What file formats can the import wizards handle?
You can import contacts and business accounts directly from an ACT! or Outlook file, or from any CSV (comma-separated values) file, such as a GoldMine or Excel file. You can import leads, solutions, custom objects, or person accounts from any CSV file.
If commas aren’t appropriate for your locale, use a tab or other delimiter.
