excelFileOut = new FileOutputStream(currentImportedFile); //currentImportedFile是当前导入的excel文件
newFormatWorkbook.write(excelFileOut); //newFormatWorkbook是用XSSF创建的workbook工作薄
excelFileOut.close(); //最后关闭谢谢了

Answer 1

安装03版excel兼容07版插件就可以了嘛

Answer 2

我不是打不开07以上版本，是程序写07以上版本有问题
我本身电脑就是装的OFFICE 2010版

Answer 3

贴代码！还有引入的jar包是否有问题！

Answer 4

poi包的版本太低，换成最新版的就可以操作xlsx了。

Answer 5

代码比较长，包的话引了POI的还有OOXML下面的三个，一共9个包
还要其它的吗？

Answer 6

poi 3.8 能操作.xls不能操作.xlsx
同求解决方法？
