Answer 1

The BULK INSERT command in SQL Server 2005 will use a tab as a field delimiter by default so there is no need to convert a tab delimited text file to csv format.

In fact, converting it to a real csv will make things more difficult. BULK INSERT will not respect quotes as a string delimiter so a true csv file that has strings encapsulated by quotes with commas somewhere in the string will break the import.
