有什么软件可以随意提取Excel表格中的数据？
推荐你使用Java进行开发，通过Apache POI开源项目实现对Excel表格的数据读取：
下载POI4.1.0:

下载POI4.1.0:

并将jar包导入项目工程。
实现代码：
public class ExcelOperate {
public static void main(String[] args) throws Exception {
File file = new File(\"ExcelDemo.xls\");
String[][] result = getData(file, 1);
int rowLength = result.length;
for(int i=0;i<rowLength;i++) {
for(int j=0;j<result[i].length;j++) {
System.out.print(result[i][j]+\"\t\t\");
}
System.out.println();
}
}
