今天,我來教你們怎麼實現Java操做Excel文件。json

import java.io.File;
import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;

import com.alibaba.fastjson.JSONArray;
import com.alibaba.fastjson.JSONObject;

public class ExcelOperate {
    public static void main(String[] args) {
        Sheet sheet;
        Workbook book;
        Cell cell1, cell2, cell3, cell4, cell5;
        JSONArray array = new JSONArray();
        try {
            // 爲要讀取的excel文件名
            book = Workbook.getWorkbook(new File("D://test.xls"));

            // 得到第一個工做表對象(ecxel中sheet的編號從0開始,0,1,2,3,....)
            sheet = book.getSheet(0);

            for (int i = 1; i < sheet.getRows(); i++) {
                // 獲取每一行的單元格
                cell1 = sheet.getCell(0, i);// (列,行)
                cell2 = sheet.getCell(1, i);
                cell3 = sheet.getCell(2, i);
                cell4 = sheet.getCell(3, i);
                cell5 = sheet.getCell(4, i);
                if ("".equals(cell1.getContents())) {// 若是讀取的數據爲空
                    break;
                }
                JSONObject object = new JSONObject();
                object.put("ID", cell1.getContents());
                object.put("編號", cell2.getContents());
                object.put("姓名", cell3.getContents());
                object.put("數量", cell4.getContents());
                object.put("住址", cell5.getContents());
                array.add(object);
            }
            System.out.println(array.toString());
            book.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}複製代碼

在這個過程當中你可能會遇到一個錯誤,以下圖:spa

這是由於不支出讀取 excel 2007 文件(.xlsx)。只支持 excel 2003 (.xls)。3d

輸入的數據格式:excel

輸出結果:code

[{"編號":"11","姓名":"黃","住址":"遼寧","ID":"1","數量":"3"},{"編號":"22","姓名":"欽","住址":"大連","ID":"2","數量":"32"},{"編號":"33","姓名":"建","住址":"開發區","ID":"3","數量":"32"},{"編號":"44","姓名":"黃","住址":"軟件學院","ID":"4","數量":"32"},{"編號":"55","姓名":"欽建","住址":"大黑山","ID":"5","數量":"3232"}]cdn
