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

Question

I have a program (below) that takes txt files and puts them into an excel spreadsheet. My goal is to extract the data from a text file but only text after the colon.

Example txt file(No space between "name:" and "phone:" lines in the txt):

Name: John doe

phone: (xxx) xxx-xxxx

I want my program to only save john doe in the excel sheet and title the column "Name": I want my program to only save (xxx) xxx-xxxx in the excel sheet and title the column "phone" I want to be able to add multiple entrys to the spreadsheet.

Example(in excel sheet generated):This is what i want it to look like!

....A..............B

1 name | Phone

2 john doe (123) 123-1234

3 jack dee (123) 123-1231

So i looked at the string split to get only data after the ":" but cant find much documentation on it. Also getting the info to line up correctly in the excel. Any help is much appreciated.

Thanks, James

If your file email.txt Always has the format you said:

Name: John
phone: (xxx) xxx-xxxx

I'm not familiarized with the row and cell creation, so I will give you some pseudo code to you understand what you have to do on your code:

On this part of your code:

//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
}
