在循環中，用getRow()替換createRow() -您已經創建了標題行（即使標題和內容顯然不匹配）。 

String table = [{}{}{}];
JSONArray arrayJson = new JSONArray(table);

FileOutputStream fos = null ;

FileInputStream fis = new FileInputStream(new File("D:/File/filename1.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook (fis);
XSSFSheet sheet = workbook.getSheetAt(0);
//Create rows
XSSFRow row0 = sheet.createRow(0);
XSSFCell r1c0 = row0.createCell(0);
r1c0.setCellValue("Name");

XSSFRow row1 = sheet.createRow(1);
XSSFCell r1c1 = row1.createCell(0);
r1c1.setCellValue("Location");

XSSFRow row2 = sheet.createRow(2);
XSSFCell r1c2 = row2.createCell(0);
r1c2.setCellValue("Distance");

XSSFRow row3 = sheet.createRow(3);
XSSFCell r1c3 = row3.createCell(0);
r1c3.setCellValue("Super built up area (in sq.ft)");

XSSFRow row4 = sheet.createRow(4);
XSSFCell r1c4 = row4.createCell(0);
r1c4.setCellValue("No of basement/s & floors");
