Identify the input CSV file by clicking on the open file button and navigating to the file.
Define an output CSV file to create in the next text box. When the input CSV is first selected, the
first line of the file is read and parsed to created a list of fields. If the first line of the CSV file
contains field names, then the names will be listed. If, however, there is no first line of field names
then the data values from the first row are listed instead. Select all the fields you wish to retain
by clicking on the check-mark box next to the field. You may preview the first N number of records from
the CSV file by clicking on the View button - the data will be displayed in a textbox at the bottom of
the form. Press OK to begin processing. You will be notified when processing is complete (note that for
large CSV files, this program can run for many seconds or even minutes).
