Example MS Excel Extraction Script with Version Support

function dumpValues(revision, file) {
 if (file !=null) {
 var wb = new WorkbookFactory.create(file);
// var sheet = wb.getSheetAt(0);
 var sheet = wb.getSheet("Tabelle1");
 for (myrow = 1; !isCellEmpty(sheet, myrow, 0); myrow++) {
 dataset.setColumnValue("A",getNumericValue(sheet,myrow,0));
 dataset.setColumnValue("B",getDateValue(sheet,myrow,1));
 dataset.setColumnValue("C",getStringValue(sheet,myrow,2));

 dataset.setColumnValue("Revision",revision.getProperty("revisionIdentifier"));

 dataset.setColumnValue("RevisionDate",revision.getProperty("date"));

 dataset.storeResultRow();
