WebDirect can export records. Why do you need Export field Contents?
Perhaps you could explain a bit more about what you're trying to do.
If you're simply trying to create a .csv file from records in an existing table, you're probably looking for the Export Records script step rather than the Export Field Contents step, since it's the records within a table you want to export, rather than just a field within a record.
Each line in the .csv file would be a record, and each comma-separated value on each line would be a field.
Does that help, or are you trying to do something more involved?
