[转]Java Jacob操作Excel的相关文章

java poi 操作excel，xssf 读excel 2007，将某些单元格为固定值

本来想看一下java IO,NIO,发现这块知识体系还挺大.暂时写一个操作excel的demo.由于时间关系,完成了功能,后期继续完善. 功能:读取excel表格(该表格为测试结果表格,共十几列,第一行是标题),将第0列标记为id(递增),第9列标记为结果(默认是PASS),第10列标记为姓名. 本可以使用excel的拖拽功能,但由于excel中的内容和样式经常需要修改,因此导致重复工作.暂写这个小demo,期待完善后功能更详尽. import org.apache.poi.hssf.userm

java poi操作excel 添加 锁定单元格保护

Excel的book保护是很常用的,主要是不想让别人修改Excel的时候用.这样能够避免恶意随便修改数据,提高数据的可信度. 下面介绍JAVA POI来实现设置book保护: 使用HSSFSheet类的protectSheet(password)方法就可以了. 具体代码如下: package com.util; import java.io.FileOutputStream; import org.apache.poi.hssf.usermodel.HSSFCell; import org.ap

java使用POI操作excel文件,实现批量导出,和导入

一.POI的定义 JAVA中操作Excel的有两种比较主流的工具包: JXL 和 POI .jxl 只能操作Excel 95, 97, 2000也即以.xls为后缀的excel.而poi可以操作Excel 95及以后的版本,即可操作后缀为 .xls 和 .xlsx两种格式的excel. POI全称 Poor Obfuscation Implementation,直译为"可怜的模糊实现",利用POI接口可以通过JAVA操作Microsoft office 套件工具的读写功能.官网:htt
