**JAVA EXCEL API**:是一开放源码项目，通过它Java开发人员可以读取Excel文件的内容、创建新的Excel文件、更新已经存在的Excel文件。

官网下载地址：[http://www.andykhan.com/jexcelapi/][http_www.andykhan.com_jexcelapi]  
下载好了以后，解压压缩包，把里面的jxl.jar加入工程的lib文件夹中。

代码：

package com.li.test;
    
    
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.io.OutputStream;
    import jxl.Workbook;
    import jxl.write.Label;
    import jxl.write.WritableSheet;
    import jxl.write.WritableWorkbook;
    import jxl.write.WriteException;
    
    public class JavaExlTest { 
        public void createExcel(OutputStream os) throws WriteException,IOException{
             //创建工作薄
            WritableWorkbook workbook = Workbook.createWorkbook(os);
            //创建新的一页
            WritableSheet sheet = workbook.createSheet("First Sheet",0);
            //创建要显示的内容,创建一个单元格，第一个参数为列坐标，第二个参数为行坐标，第三个参数为内容
            Label xuexiao = new Label(0,0,"学校");
            sheet.addCell(xuexiao);
            Label zhuanye = new Label(1,0,"专业");
            sheet.addCell(zhuanye);
            Label jingzhengli = new Label(2,0,"专业竞争力");
            sheet.addCell(jingzhengli);
    
            Label qinghua = new Label(0,1,"清华大学");
            sheet.addCell(qinghua);
            Label jisuanji = new Label(1,1,"计算机专业");
            sheet.addCell(jisuanji);
            Label gao = new Label(2,1,"高");
            sheet.addCell(gao);
    
            Label beida = new Label(0,2,"北京大学");
            sheet.addCell(beida);
            Label falv = new Label(1,2,"法律专业");
            sheet.addCell(falv);
            Label zhong = new Label(2,2,"中");
            sheet.addCell(zhong);
    
            Label ligong = new Label(0,3,"北京理工大学");
            sheet.addCell(ligong);
            Label hangkong = new Label(1,3,"航空专业");
            sheet.addCell(hangkong);
            Label di = new Label(2,3,"低");
            sheet.addCell(di);
    
            //把创建的内容写入到输出流中，并关闭输出流
            workbook.write();
            workbook.close();
            os.close();
        }
    
        public static void main(String[] args) throws WriteException, IOException {
            OutputStream fileOut = new FileOutputStream("D:/2.xls");
            JavaExlTest sw = new JavaExlTest();
            sw.createExcel(fileOut);
    
        }
    }
