Unable To Write Multiple Lines in Excel Using POI

Question

I have a situation where I will be reading multiple lines and after some logic I need to write the lines in an Excel Sheet. I am using Apache POI for this purpose. However, the problem that I am facing is that, only the last line (from the loop) is being written to the Excel

Can someone please help me on this or provide some code snippet?

Thanks

Answer 1

    Workbook wb = new XSSFWorkbook();   //or new HSSFWorkbook();
    Sheet sheet = wb.createSheet();

    Row row = sheet.createRow(2);
    Cell cell = row.createCell(2);
    cell.setCellValue("Use \n with word wrap on to create a new line");

    //to enable newlines you need set a cell styles with wrap=true
    CellStyle cs = wb.createCellStyle();
    cs.setWrapText(true);
    cell.setCellStyle(cs);

    //increase row height to accomodate two lines of text
    row.setHeightInPoints((2*sheet.getDefaultRowHeightInPoints()));

    //adjust column width to fit the content
    sheet.autoSizeColumn((short)2);

    FileOutputStream fileOut = new FileOutputStream("ooxml-newlines.xlsx");
    wb.write(fileOut);
    fileOut.close();
