BlueIntegrator now supports CSV and other delimited files directly. Within the Schema Editor just select CSV or CSV_WithHeader from the IsFlatFile property drop-down menu of the schema root, and provide the basic details requested or a sample file.  CSV_WithHeader includes a header line with field names on the first line.  You can also access this function by going to the Special Schemas item on the Tools menu of the BlueIntegrator Schema Editor. See Special Schemas: CSV Files.
