Remove Software info from generated with JasperReports report at Excel format

Question

I'm creating an XLS report using JasperReports with code:

JRXlsExporter exporter = new JRXlsExporter();

exporter.setExporterInput(new SimpleExporterInput(compile(report)));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(stream));

SimpleXlsReportConfiguration configuration = new SimpleXlsReportConfiguration();

configuration.setOnePagePerSheet(TRUE);

exporter.setConfiguration(configuration);
exporter.exportReport();

I need to remove Software information from the xls file metadata

The result of running exiftool Vinculaciones.xls command:

Try adding these lines:

    SimpleXlsExporterConfiguration exportConfig = new SimpleXlsExporterConfiguration();
    exportConfig.setMetadataApplication("");
    exporter.setConfiguration(exportConfig);

This won't remove the Software metadata field, but it would put an empty value for it. If you want to completely remove the field you'll have to change/extend the exporter code, e.g. like this:

    JRXlsExporter exporter = new JRXlsExporter() {
        @Override
        protected void openWorkbook(OutputStream os) {
            super.openWorkbook(os);
            workbook.getSummaryInformation().removeApplicationName();
        }           
    };
