Typically an ARFF data file is comprised of two sections: a header that defines the data source and schema, and the data section, which contains the actual entities and their attributes. The header for an ARFF file defines the list of the attributes in columns and their data types. The header can also contain multiple comment lines that describe the data source or any other notes.
If the dataset you are converting does not have column names, use the Edit Metadata module to add column names before using converting to ARFF.
