You could be talking about writing to a CSV file, or Comma Separated Values. That is NOT an Excel file. It's a simple text file where each line in the file is considered a record and each value in a record is written with some kind of delimiter between values, like a comma or tab character.

Thank you for your time , in the problem statement it is given that we have to read data from txt file and if it's palindrome then we have to write it into excel file and if it's string we have to count length of each string

This is a school assignment. I seriously doubt you have to create an actual Excel file. It's possible your teacher is using the term Excel to refer to a CSV file. You better when with your teacher to make sure.

Where did you find this question? You cannot create Excel files by simple filehandling. You need to find a Java library that supports the creation of Excel files.

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
