I have the following code that reads a spreadsheet and writes to pipe-delimeted file. Rows have differing length. The last cell shouldn't get appended with a pipe character (but does). I tried things like https://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Row.html#getLastCellNum() but cannot make it work.
XSSFWorkbook wb = new XSSFWorkbook(pathandfilename);
for (int i = 0; i < wb.getNumberOfSheets(); i++) {
XSSFSheet sheet = wb.getSheetAt(i);
String outfilename = path + "\\" + prefix + sheetname + postfix;
PrintWriter outfilewriter = new PrintWriter(outfilename, "UTF-8");
Iterator<Row> rowIterator = sheet.iterator();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
cell.setCellType(Cell.CELL_TYPE_STRING);
outfilewriter.print(cell.getStringCellValue() + "|");
}
outfilewriter.print("\n");
}
outfilewriter.close();
}
wb.close();
