Jasper Reports Excel output

问题

I need to generate a report in Excel format using Jasperreports. I am using iReports 3.7.0 The reports gets generated with no issues except the size of empty cells.

Can somebody please tell how to avoid the highlighted cell being enlarged. Also the normal cells are also a little larger than their content.

Also,I would say stick to basics when you need to export Japser to XLS. I mean no graphics, and more.

The above solution is good for generating XLS from iReport.

If you would like to generate XLS thru program; use the following code

exporter = new JRXlsExporter();
exporter.setParameter(JRXlsExporterParameter.IS_COLLAPSE_ROW_SPAN, Boolean.TRUE);
exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_COLUMNS, Boolean.TRUE);
exporter.setParameter(JRXlsExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);
exporter.setParameter(JRXlsExporterParameter.IS_ONE_PAGE_PER_SHEET, Boolean.FALSE);
exporter.setParameter(JRXlsExporterParameter.IS_DETECT_CELL_TYPE, Boolean.FALSE);
exporter.setParameter(JRXlsExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);
exporter.setParameter(JRXlsExporterParameter.IS_IGNORE_GRAPHICS, Boolean.TRUE);

I got the answer. Thought of sharing it with others. Below is the setting.

Also - if you're deploying to jasperserver you can set the custom properties within the report. (iReport doesn't do this automatically)

In the properties of the main report element add:

net.sf.jasperreports.export.xls.collapse.row.span
net.sf.jasperreports.export.xls.remove.empty.space.between.columns
net.sf.jasperreports.export.xls.remove.empty.space.between.rows

and set them all to true
