Question

我有一个程序（下面），它接受txt文件并将它们放入excel电子表格中。我的目标是从文本文件中提取数据，但只在冒号后提取文本。

示例txt文件（txt中“name：”和“phone：”行之间没有空格）：

姓名：John doe

电话：（xxx）xxx-xxxx

我希望我的程序只在excel表中保存john doe并标题为“Name”列：我希望我的程序只在excel表中保存（xxx）xxx-xxxx，标题为“phone”列我希望能够在电子表格中添加多个信息。

示例（在excel表中生成）：这就是我想要的样子！

....一个..............乙

1个名字|电话

2 john doe（123）123-1234

3 jack dee（123）123-1231

所以我查看了字符串split以获取“：”之后的数据，但无法找到很多文档。还要使信息在Excel中正确排列。非常感谢任何帮助。

谢谢，詹姆斯

如果您的文件email.txt始终具有您所说的格式：

Name: John
phone: (xxx) xxx-xxxx

我对行和单元格的创建并不熟悉，所以我会给你一些伪代码，让你明白你要对你的代码做些什么：

在你的代码的这一部分：

//create a count for rows here
inr rowNumber = 0;
//Here you are reading your list with all data readed
for(int i=0;i<arr.size()-1;i+=2){ //the -1 is for the array to stop on the 
                                 //last but one row

    row = spreadSheet.createRow((short) rowNumber); //external count

    //pseudocode from here
    cell1 = row.createCell(0); 
    cell2 = row.createCell(1); 

    cell1.setCellValue(  arr.get(i).substring(arr.get(i).indexOf(":")+1) );
                              // ^ this is for name
    cell2.setCellValue(  arr.get(i+1).substring(arr.get(i+1).indexOf(":")+1) );
                               // ^ this is for phone

    rowNumber++; //increment your rowNumber
}

如何从txt文件中获取数据并将其发送到excel电子表格？（我只想在txt文件中的“：”之后的所有内容）？
