Jasperreports export to excel

Here is my code but take care with the version implemented.
Notice : Export excel with ireport, for ireport 6.0 , java 7

 Map<String, Object> parametro = new HashMap<String, Object>();
                parametro.put("USUARIO", UConstante.NAME_MINISTERIO_USER);
                parametro.put("RUTA_LOGO", PuenteFile.getRutaFiles(FacesContext.getCurrentInstance(), PuenteFile.RUTA_IMG_LOGO));
                parametro.put("PATH_SYSTEM", rutaFileSystemHD);
                parametro.put("WHERE_DATA", WHERE_REGISTRO);
                parametro.put("WHERE_PROYECTO_USUARIO", WHERE_PROYECTO_USUARIO);
                parametro.put("WHERE_ZONA", WHERE_ZONA);
                parametro.put("NAME_APP", RutaFile.NAME_APP);
                parametro.put("ID_USUARIO", getUsuario().getId());
                parametro.put("ID_PROYECTO", beanProyecto.getId());
                parametro.put("SUBREPORT_DIR", SUBREPORT_DIR);

                System.out.println(">>>>>> PARAMETROS :" + parametro.toString());

              try {
                    JasperPrint jasperPrint = JasperFillManager.fillReport(path, parametro, PgConnector.getConexion());
                    JRXlsExporter xlsExporter = new JRXlsExporter();
                    xlsExporter.setExporterInput(new SimpleExporterInput(jasperPrint));
                    xlsExporter.setExporterOutput(new SimpleOutputStreamExporterOutput(PATH_REPORT_FILE + nameExcel);
                    SimpleXlsReportConfiguration xlsReportConfiguration = new SimpleXlsReportConfiguration();
                    SimpleXlsExporterConfiguration xlsExporterConfiguration = new SimpleXlsExporterConfiguration();
                    xlsReportConfiguration.setOnePagePerSheet(true);
                    xlsReportConfiguration.setRemoveEmptySpaceBetweenRows(false);
                    xlsReportConfiguration.setDetectCellType(true);
                    xlsReportConfiguration.setWhitePageBackground(false);
                    xlsExporter.setConfiguration(xlsReportConfiguration);
                    xlsExporter.exportReport();

                } catch (Exception ex) {
                    ex.printStackTrace();
                }

and for lower versions of ireport 5.6

          try {
                   JasperPrint jasperPrint = JasperFillManager.fillReport(new FileInputStream(path), parametro, PgConnector.getConexion());
                    JRXlsExporter exporterXLS = new JRXlsExporter();
                    exporterXLS.setParameter(JRXlsExporterParameter.JASPER_PRINT, jasperPrint);
                    exporterXLS.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
                    exporterXLS.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.TRUE);
                    exporterXLS.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
                    exporterXLS.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
                    exporterXLS.setParameter(JRXlsExporterParameter.OUTPUT_FILE_NAME,PATH_REPORT_FILE + nameExcel);
                    exporterXLS.exportReport();
                } catch (Exception ex) {
                    ex.printStackTrace();

                }

We have seen in the previous chapter, how to print and view a JasperReport generated document. Here, we shall see how to transform or export these reports into other formats such as PDF, HTML, and XLS. Facade class net.sf.jasperreports.engine.JasperExportManager is provided to achieve this functionality. Exporting means transforming the JasperPrint object (.jrprint file) into different format.

The following code (JasperReportExport.java) demonstrates the exporting process of the JasperReport document. The JasperExportManager provides methods to export a report into PDF, HTML, and XML only. To export to the XLS format, we have used the class net.sf.jasperreports.engine.export.JRXlsExporter. This code generates following three files −

• sample_report.pdf
• sample_report.html
• sample_report.xls

Exporting to Other Formats

Let’s write a report template. The contents of the JRXML file (C:toolsjasperreports-5.0.1testjasper_report_template.jrxml) are as below −

<?xml version = "1.0" encoding = "UTF-8"?>

</jasperReport>

Next, contents of the POJO file C:toolsjasperreports-5.0.1testsrccomtutorialspointDataBean.java are as given below −

package com.tutorialspoint;

public class DataBean {
   private String name;
   private String country;

   public String getName() {
      return name;
   }

   public void setName(String name) {
      this.name = name;
   }

   public String getCountry() {
      return country;
   }

   public void setCountry(String country) {
      this.country = country;
   }
}

The contents of the file C:toolsjasperreports-5.0.1testsrccomtutorialspointDataBeanList.java are as given below −

package com.tutorialspoint;

import java.util.ArrayList;

public class DataBeanList {
   public ArrayList<DataBean> getDataBeanList() {
      ArrayList<DataBean> dataBeanList = new ArrayList<DataBean>();

      dataBeanList.add(produce("Manisha", "India"));
      dataBeanList.add(produce("Dennis Ritchie", "USA"));
      dataBeanList.add(produce("V.Anand", "India"));
      dataBeanList.add(produce("Shrinath", "California"));

      return dataBeanList;
   }

   /**
    * This method returns a DataBean object,
    * with name and country set in it.
    */
   private DataBean produce(String name, String country) {
      DataBean dataBean = new DataBean();
      dataBean.setName(name);
      dataBean.setCountry(country);
      
      return dataBean;
   }
}

Write a main class file JasperReportFill.java, which gets the java bean collection from the class (DataBeanList) and passes it to the JasperReports engine, to fill the report template. Save it to the directory C:toolsjasperreports-5.0.1testsrccomtutorialspoint.

package com.tutorialspoint;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;

import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;
import net.sf.jasperreports.engine.export.JRXlsExporter;

public class JasperReportFill {
   @SuppressWarnings("unchecked")
   public static void main(String[] args) {
      String sourceFileName = "c://tools/jasperreports-5.0.1/"
         + "test/jasper_report_template.jasper";
      String printFileName = null;
      DataBeanList DataBeanList = new DataBeanList();
      ArrayList<DataBean> dataList = DataBeanList.getDataBeanList();
      JRBeanCollectionDataSource beanColDataSource =
         new JRBeanCollectionDataSource(dataList);

      Map parameters = new HashMap();
      try {
         printFileName = JasperFillManager.fillReportToFile(sourceFileName,
            parameters, beanColDataSource);
         if (printFileName != null) {
            /**
             * 1- export to PDF
             */
            JasperExportManager.exportReportToPdfFile(printFileName,
               "C://sample_report.pdf");

            /**
             * 2- export to HTML
             */
            JasperExportManager.exportReportToHtmlFile(printFileName,
               "C://sample_report.html");

            /**
             * 3- export to Excel sheet
             */
            JRXlsExporter exporter = new JRXlsExporter();

            exporter.setParameter(JRExporterParameter.INPUT_FILE_NAME,
               printFileName);
            exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,
               "C://sample_report.xls");

            exporter.exportReport();
         }
      } catch (JRException e) {
         e.printStackTrace();
      }
   }
}

Here, we have included the logic to export the jasper print file to pdf, html and xls format.

Generating Reports

Let’s compile and execute above files using our regular ANT build process. The build.xml file is as given below −

<?xml version = "1.0" encoding = "UTF-8"?>
<project name = "JasperReportTest" default = "executereport" basedir = ".">
   <import file = "baseBuild.xml"/>

   <target name = "executereport" depends = "compile,compilereportdesing,run">
      <echo message = "Im here"/>
   </target>
   
   <target name = "compilereportdesing" description = "Compiles the JXML file and
      produces the .jasper file.">
      
      <taskdef name = "jrc"
         classname = "net.sf.jasperreports.ant.JRAntCompileTask">
         <classpath refid = "classpath" />
      </taskdef>
      
      <jrc destdir = ".">
         <src>
            <fileset dir = ".">
               <include name = "*.jrxml" />
            </fileset>
         </src>
         <classpath refid = "classpath" />
      </jrc>
   
   </target>
	
</project>

Go to the command prompt and then go to the directory C:toolsjasperreports-5.0.1test, where build.xml is placed. Finally, execute the command ant -Dmain-class=com.tutorialspoint.JasperReportFill. The output is as follows −

C:toolsjasperreports-5.0.1test>ant -Dmain-class=com.tutorialspoint.JasperReportFill

BUILD SUCCESSFUL
Total time: 32 seconds

As the result of above execution, you will find three files sample_report.pdf, sample_report.html, sample_report.xls generated in the C: directory.

In Main Report, Report properties, Page Format (for this one example report I am looking at), my Page Format has the following properties:

• Format: Letter is what I always use
• Width: When I have a report that does both PDF and Excel, the the width is 792.
• Height: When I have report that does both PDF and Excel, then the height is 612
  Note: Excel doesn’t care what your margins here are. PDF likes these just fine.
• Units: pixel. Much easier to work in than inches
• Page Orientation: Landscape
• Margins: 36 for all margins.

Also, in Report properties, I have made these selections:

• When No Data Type: No Data Section
• Summary On A New Page: checked
• Summary with Page Header and Footer: checked –I could have this unchecked, and in the Summary section, I would have to add the report name and the company logo.
• Ignore Pagination: After much experiementation, I have decided that unchecked is best, otherwise when doing a PDF or Excel format report, the PDF does not page properly, and can’t be recovered from. It is the lessor of two evils (until Jaspersoft fixes this in a new version).

Also, in the Main Report Properties, in Advanced, Properties, I have added these (which end up near the top of the Source XML):

<property name = "net.sf.jasperreports.export.xls.one.page.per.sheet" value="true"/>

Without the above, JS only puts as many data rows on a single tab as fit within the Page Height.

<property name="net.sf.jasperreports.export.xls.remove.empty.space.between.rows" value="true"/>

The above gets rid of one row with a very large row height at the end of the data tab. Don’t understand why that one very high row is created, but this is needed to get rid of it. Of course having this means that you can’t (easily) have row spacing in the footnotes.

<property name="net.sf.jasperreports.export.xls.remove.empty.space.between.columns" value="true"/>

The above gets rid of empty columns, such as caused by margins, or by poor layout.

<property name="net.sf.jasperreports.export.xls.white.page.background" value="false"/>

The above shows the Excel grid lines, otherwise you get solid white, which kind of ruins the look of Excel (for a data dump).

<property name="net.sf.jasperreports.export.xls.detect.cell.type" value="true"/>

The above tells Excel to treat dates as dates, numbers as numbers, instead of all being treated as text when it is set to “false” (which is the default).
Note: Java’s custom date formats are different from Excel’s custom date formats, so a date format might look good in Excel but bad in Java/HTML, or vis-a-versa, so take care with custom date formats.

<property name="net.sf.jasperreports.export.xls.ignore.graphics" value="false"/>

The above tells Excel to not delete the company logo graphic. “true” (which is the default) deletes graphics.

<property name="net.sf.jasperreports.page.break.no.pagination" value="apply"/>

The above, as far as I know, has to be typed or cut-n-pasted directly into the Source XML. I have not found a place to select it under any Properties. I am not certain why it is needed, but it is.

<property name="net.sf.jasperreports.export.xls.sheet.names.all" value="Data/Footnotes"/>

The above tells Excel, to name the first tab “Data”, and the second tab “Footnotes”. Instead of “Data”, I would recommend something more descriptive, maybe the report name.

<property name="net.sf.jasperreports.export.xls.freeze.row" value="3"/>

The above tells Excel to freeze the top 2 rows. Once in Excel therefore, the report name/company logo row, and the column headers row is frozen, and the user can scroll through thousands of records and still see them. Without this, the user would have had to do it themselves.

<property name="net.sf.jasperreports.print.keep.full.text" value="true"/>

The above keeps JS from truncating values wider than the explicity set colunmn widths. In Excel this is seen as wrapping.

<property name="net.sf.jasperreports.exports.xls.font.size.fix.enabled" value="false"/>

The above keeps JS from reducing the font size by 1 when exporting to Excel. For example, without this, an Arial 10 in Studio, in Server when exported to Excel ends up as an Arial 9 font.

The following Report Export properties are used by the exporters to create default exporter filter instances that filter out content based on element origin information:

net.sf.jasperreports.export.{format}.exclude.origin.{suffix}.{arbitrary_name}
net.sf.jasperreports.export.{format}.exclude.origin.keep.first.{suffix}.{arbitrary_name}

Where:

• {format} is one of pdf, html, xls, rtf, odt, csv, txt
• {suffix} is one of band, group, report

This Post will explain , How to export different formats using Jasper and Jrxml using java

Step 1: Download Download Jasper Studio
or I Report Designer

Step 2 : Design your page by providing connection details and query details and what columns needs to be display in PDF/excel/CSV

Step 3: Your design Page details can be mentioned in Summary Band.

Step 4: Once design completes , then it is time to write java class to export into different formats

With Java

Export to xlsx format

try (InputStream inputStream = JRLoader.getResourceInputStream(path)) {  // read report as input stream 
    JasperReport  jasperReport = JasperCompileManager.compileReport(JRXmlLoader.load(inputStream)); // compile report

    Map<String, Object> params = new HashMap<>(); // init map with report's parameters
    params.put(JRParameter.REPORT_LOCALE, Locale.US);
    params.put(JRParameter.IS_IGNORE_PAGINATION, true);
    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, connection);  // prepare report - passs parameters and jdbc connection

    JRXlsxExporter exporter = new JRXlsxExporter(); // initialize exporter 
    exporter.setExporterInput(new SimpleExporterInput(jasperPrint)); // set compiled report as input
    exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(destFile));  // set output file via path with filename
    SimpleXlsxReportConfiguration configuration = new SimpleXlsxReportConfiguration();
    configuration.setOnePagePerSheet(true); // setup configuration
    configuration.setDetectCellType(true);
    exporter.setConfiguration(configuration); // set configuration
    exporter.exportReport();
}

Adding autofilter for columns

The using of net.sf.jasperreports.export.xls.auto.filter property allow to add autofilter in generated xls file.

<columnHeader>
    <band height="30" splitType="Stretch">
        <staticText>
            <reportElement x="0" y="0" width="100" height="20">
                <property name="net.sf.jasperreports.export.xls.auto.filter" value="Start"/>
            </reportElement>
            <text><![CDATA[First column with filter]]></text>
        </staticText>
        <staticText>
            <reportElement x="100" y="0" width="100" height="20"/>
            <text><![CDATA[Second column with filter]]></text>
        </staticText>
        <staticText>
            <reportElement x="200" y="0" width="100" height="20">
                <property name="net.sf.jasperreports.export.xls.auto.filter" value="End"/>
            </reportElement>
            <text><![CDATA[Third (Last) column with filter]]></text>
        </staticText>
        <staticText>
            <reportElement x="300" y="0" width="100" height="20"/>
            <text><![CDATA[Fourth column without filter]]></text>
        </staticText>            
    </band>
</columnHeader>

The property can be set in Jaspersoft Studio with help of context menu or manually by editing jrxml file.
