Use a third party library like apache poi for reading Excel data in Java.
You might want to try the jexcelapi found on sourceforge: JExcelApi
Very easy to use to read & write excel files from java.
You use Java Excel API. This is an excellent article that demonstrates reading from and writing to Excel with Java.
Here is the Java Excel API download.

I am trying to read data from database and then need to write the data to an excel/csv file in an java application. The data from database can be more than 10000 rows. So could someone suggest a nice solution taking into account the performance issue also.
Is there a way we can directly read and write to excel sheet.
Thanks in advance,
Kathy.
You can use Apache POI to do this: http://poi.apache.org
Use the HSSFWorkbook as an abstraction of a .xls workbook. There's also a XSSF format for the newer XML-based Excel files (.xlsx, etc).
Apache POI will best suits to your problem.
Try the following references example and document.
http://poi.apache.org/
http://viralpatel.net/blogs/java-read-write-excel-file-apache-poi/
The second reference will give you the whole implementation of how to work with POI.
When it comes to java excel you should try out Apache POI.
Apache has a nice library that should meet your requirements.
Look into http://poi.apache.org/
Hope this helps.

Since you tagged the question with java, I think you are using the Java language binding.
Just download and add to your project the Apache POI library and then you can read the Excel input file.
You can iterate all the rows in the first column and store them in an ArrayList<String> or any other data structure that fits your needs before starting the test. Here's a quick guide on reading a spreadsheet file.
The code you need is here:
1. open the file as a Workbook
2. get the cell contents
Another options could be saving your values in a CSV file (easier coding), but I understand that Excel is so commonly used that it comes very handy to let everyone create input files for data-driven tests.
I want to make a program that takes and isbn number and searches the web for the information about the book assosciated with that number and then store that information in an excel sheet. I am not sure how to go about doing this.
I was thinking about making a Java program that uses the JSoup library to retrieve information from a url and then simply putting that information in a text file so the user can manually copy and paste it into an excel sheet, but there has to be a direct way. Any help would be appreciated. Thankyou.

Then you can use Java Excel API to enter to the excel sheet.

apache project for manipulating excel in java
I have 200,000 or more records in an Excel file. If I tried to read records row by row and create a CSV file it's very costly as well as time consuming. Is there any API that can help me with that?
There are several frameworks out there, if you have a look.
For example, you can try:
Apache POI (example)
JExcel (example)
This seems to be the same question as How to import an Excel file into MySQL using ODBC in Java?
What has changed? If you want to write to a CSV file you should use a CSV library such as OpenCSV: http://opencsv.sourceforge.net/
I am trying to make a program through which i want to manipulate data in the excel sheet,
But data is being manipulated only when the excel sheet is open.
whats the process to open and close it using java coding.
You can use POI to read and write Excel sheets.
This article is interesting to understand how to use it :

Hey look, there's a tutorial on how to do this link from the JExecel website!

Side note: It looks like JExcel is file based only. This means you can't interact with an open spreadsheet. If you need to interact with an open spreadsheet you will have to use JNI or a library such as J-Integra COM, which uses JNI.
