I want to write a program that compares two Microsoft Excel sheets using Java.
Is there any existing library (and its documentation) that can help me get started with basic stuffs like reading all the rows and columns of the excel ?
Have a look at Apache POI, which is a Java API for Microsoft Documents.
And here is a tutorial on how to setup and get started with Excel files.
1. Apache POI
Apache POI, a project run by the Apache Software Foundation, and
previously a sub-project of the Jakarta Project, provides pure Java
libraries for reading and writing files in Microsoft Office formats,
such as Word, PowerPoint and Excel.
http://poi.apache.org/
2. docx4j
docx4j is a Java library for creating and manipulating Microsoft Open XML (Word docx, Powerpoint pptx, and Excel xlsx) files.

When saving an excel sheet (xls - 2330) in .xml form, the xmlss file will contain the respective xsl code. But in xlsx i can't save the file with .xml format.
Also is there any specific Apache POI API availabe to convert .xls (2003) to .xlsx(2007) format?
Since the POI creates the xmlss file to create the xlsx, is there any simpler option?

How to get column name of Excel sheets using Java? I am using jexcel package for reading from and writing into excel sheet. And also how to change a column name of an Excel sheet?
Which version of Java and Excel are you talking about?
For all versions of Excel till Excel 2003 you can use http://jexcelapi.sourceforge.net/.
For 2007, you can use http://poi.apache.org/index.html
I do not know of any Java APIs for Excel 2010. Sorry about that!
POI supports Excel 2010 as well. Using the XSSF library is suggested as the xlsx files tend to be slower to parse:
