Exporting to Excel
It is not uncommon to request reports in Microsoft Excel format since Excel allows
easy manipulation of report data to perform calculations. JasperReports provides
built-in capability to export reports to Excel. The following example demonstrates
this functionality:
package net.ensode.jasperbook;
import java.io.File;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;
