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.

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!
http://www.andykhan.com/jexcelapi/tutorial.html
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.

Is there any way to update excel content in background when the sheet is in open state.
I am using Apache POI Spreadsheet API (java based API) to read and write content in excel sheet.
By using user API, I am saving data to excel sheet, but I didn't find any API to update excel data in background(without closing excel file, content should be updated).
If we try to update excel when it's open it'll show error like file is accessed by other resource.
Please help me to find an API to achieve this by using Apache POI or any other API.
(I observed by using VB script we can achieve this. but first preference is Java, if there is no other API available then VB Script).
Excel puts a lock on the file and thus actively prevents other applications from changing the file, so I don't think this is possible with any library.

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.
