jasper reports - How do I Export to CSV Without Header & Footer repeating?

I want to export to CSV with the Header and Footer only showing once

The current output:
Name   Address Hobby
AAA    US      XXXXX
BBB    UK      XXXXX
(Footer)
Name   Address Hobby
CCC    ID      XXXXX
DDD    CC      XXXXX
(Footer)
Name   Address Hobby
EEE    SA      XXXXX
FFF    ZM      XXXXX
(Footer)

The desired output:
Name   Address Hobby
AAA    US      XXXXX
BBB    UK      XXXXX
CCC    ID      XXXXX
DDD    CC      XXXXX
EEE    SA      XXXXX
FFF    ZM      XXXXX
(Footer)

So how do I get the Header and footer to only show once ?

EDIT:

Footer looks like

Version : 1.0.0
AcademicProgramBusinessEntityCentreDoma Execution Time : 00:00:00.00
/NWU/StudentInformation/AcademicProgramDevelopment Build: v1.0.9 - Dev

You can use net.sf.jasperreports.export.{format}.exclude.origin.{suffix}.{arbitrary_name}(see the http://jasperreports.sourceforge.net/config.reference.html page for details) property for excluding bands (Page Header and Page Footer in your case) for exporter.

The sample:

The input data, csv file (datasource):

AAA,US,XXXXX
BBB,UK,XXXXX
CCC,ID,XXXXX
DDD,CC,XXXXX
EEE,SA,XXXXX
FFF,ZM,XXXXX

The jrxml file:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="exclude_band_for_csv" language="groovy" pageWidth="595" pageHeight="120" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="0" bottomMargin="0" uuid="daaa60dc-b91b-4e9b-bbc0-6189af985ef9">
    <property name="net.sf.jasperreports.export.csv.exclude.origin.band.1" value="pageHeader"/>
    <property name="net.sf.jasperreports.export.csv.exclude.origin.band.2" value="pageFooter"/>
    <queryString>
        <![CDATA[]]>
    </queryString>
    <field name="Name" class="java.lang.String"/>
    <field name="Address" class="java.lang.String"/>
    <field name="Hobby" class="java.lang.String"/>
    <pageHeader>
        <band height="35" splitType="Stretch">
            <staticText>
                <reportElement uuid="9da294e6-b5b7-489f-9469-7edb539315da" x="117" y="0" width="380" height="20"/>
                <textElement textAlignment="Center" verticalAlignment="Middle">
                    <font size="14"/>
                </textElement>
                <text><![CDATA[Page Header]]></text>
            </staticText>
        </band>
    </pageHeader>
    <detail>
        <band height="20" splitType="Stretch">
            <textField>
                <reportElement uuid="6a615d39-86f1-4a74-8ae7-4f8ca8e19afe" x="0" y="0" width="100" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$F{Name}]]></textFieldExpression>
            </textField>
            <textField>
                <reportElement uuid="df0929d2-34c0-4561-ab98-e6e5ce37fd11" x="100" y="0" width="100" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$F{Address}]]></textFieldExpression>
            </textField>
            <textField>
                <reportElement uuid="675381d8-57b3-427f-88e4-ec4725ea3462" x="200" y="0" width="100" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$F{Hobby}]]></textFieldExpression>
            </textField>
        </band>
    </detail>
    <pageFooter>
        <band height="45" splitType="Stretch">
            <staticText>
                <reportElement uuid="9da294e6-b5b7-489f-9469-7edb539315da" x="127" y="10" width="380" height="20"/>
                <textElement textAlignment="Center" verticalAlignment="Middle">
                    <font size="14"/>
                </textElement>
                <text><![CDATA[Page Footer]]></text>
            </staticText>
        </band>
    </pageFooter>
</jasperReport>

The report's design in iReport:

Report's design in iReport

The result of JRPdfExporter will be:

The result of generating the report in *PDF* format

Both bands are present in PDF file

The result of JRCsvExporter will be (the output csv file):

AAA,US,XXXXX
BBB,UK,XXXXX
CCC,ID,XXXXX
DDD,CC,XXXXX
EEE,SA,XXXXX
FFF,ZM,XXXXX

Both bands are absent in CSV file.

As you can see I've excluded two bands (Page Header and Page Footer) only for JRCsvExporter.
