Hi, we are currently using ireports 5.6.0, jasperreports-6.3.0, poi-3.12 and Spring framework 4.2.5 libraries in our application. We are constructing this jasperreport with help of spring framework bean. <bean id="abcExcel" class="org.springframework.web.servlet.view.jasperreports.JasperReportsMultiFormatView"> <property name="url"> <value>/reports/abcExcel.jasper</value> </property> [/code]<property name="contentDispositionMappings"> <props> <prop key="xls">inline; filename=abcExcel.xls</prop> </props> </property> <property name="exporterParameters"> <map> <entry key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS" value="true"/> <entry key="net.sf.jasperreports.engine.export.JRXlsAbstractExporterParameter.IS_ONE_PAGE_PER_SHEET" value="false"/> [/code] <entry key="net.sf.jasperreports.engine.export.JRXlsAbstractExporterParameter.IS_DETECT_CELL_TYPE" value="true"/> </map> </property> </bean> [/code]After downloading the xls file we were not able to open the sheet and getting a popup with text " Excel found unreadable content in 'xxx.xls'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click yes.". This issue is observed only when excel sheets are downloaded from IE11 and works fine with chrome download.
