CSV File Reader

Overview

Use the CSV File Reader to read comma separated files that includes a one line header (see below for format) describing the fields. It can also be used to import data exported from a DVT table view (as exported data is compliant to the format).

Input Channel

None

Output Channel

The CSV File Reader has one output channel which streams a record for each comma separated record in the input file. The comma separated record is decoded according to the information specified in the file header.
