How to hide group header from CSV export of a JRXML report

Requirement:
To hide group header from CSV export of the JRXML report.

Solution:
Use below two properties to hide the group header from the CSV export of your JRXML report:

<property name="net.sf.jasperreports.export.csv.exclude.origin.band.2" value="groupHeader"/>

<property name="net.sf.jasperreports.export.csv.exclude.origin.group.2" value="<group header name>"/>

So, for example, if the group header name is Dummy, the above property will be:
<property name="net.sf.jasperreports.export.csv.exclude.origin.group.2" value="Dummy"/>

A sample test JRXML report is attached for reference.
