        for (int i = 0; i < 10; i++) {
            ExcelCell cell = worksheet.getCell(i, 0);


        WorksheetProtection protectionSettings = worksheet.getProtectionSettings();
        worksheet.getCell(3, 2).setValue("Sheet password is 123 (only supported for XLSX and XLS file format).");

        // Supported only for XLSX file format.
