public class ExcelDataSource
extends AbstractPoiXlsDataSource

This data source implementation reads an XLSX or XLS stream.

The default naming convention is to name report fields COLUMN_x and map each column with the field found at index x in each row (these indices start with 0). To avoid this situation, users can either specify a collection of column names or set a flag to read the column names from the first row of the XLSX or XLS file.
