        Workbook workbook = new Workbook();
        //Load an Excel file
        workbook.loadFromFile("report.xlsx");

        //Get the first worksheet
        Worksheet sheet = workbook.getWorksheets().get(0);

        //Specify the cells where you want to add page breaks to
        CellRange cell1 = sheet.getRange().get("A9");
        CellRange cell2 = sheet.getRange().get("E1");

        //Add a horizontal page break
        sheet.getHPageBreaks().add(cell1);

        //Add a vertical page break
        sheet.getVPageBreaks().add(cell2);

        //Set view mode to Preview in order to view the page breaks
        sheet.setViewMode(ViewMode.Preview);

        //Save the result file
        workbook.saveToFile("ExcelPageBreaks.xlsx", ExcelVersion.Version2013);
