Question

I\'m working on JasperReport Report that generates Excel file. For some reason my cell formats/types are not how they should be. For example I have Date object in my cell bu

Answer 1

The problem is/was that because I'm using POI 3.5 and JasperReports 3.7.0 and Generating XLSX Excel format. POI 3.5 will be supported in JasperReports 3.7.1 (or just get snapshot from SVN). So what I did I just went back to the old Excel type (xls) file and it worked perfect.

Answer 2

Just FYI

setParameter(JRXlsExporterParameter.IS_AUTO_DETECT_CELL_TYPE, Boolean.TRUE); 

or IS_DETECT_CELL_TYPE, Boolean.TRUE is the one which makes the Date to change to number .

Answer 3

In new version of JasperReports the parameter net.sf.jasperreports.export.xls.pattern was introduced.

The sample:

<textField pattern="EEE, MMM d, yyyy">
    <reportElement x="100" y="12" width="75" height="11">
        <property name="net.sf.jasperreports.export.xls.pattern" value="ffffd, mmm d, yyyy"/>
    </reportElement>
    <textElement textAlignment="Right"/>
    <textFieldExpression class="java.sql.Timestamp"><![CDATA[$F{dateField}]]>
    </textFieldExpression>
</textField>

Information about this parameter is here. The sample of using is here.
