JExcel is a library for integrating Microsoft Excel into Swing applications and for working with Excel workbooks and worksheets from Java programs.

JExcel functionality can be divided into the following main parts:
# Automation of an Excel application, workbooks, worksheets, etc.
This is the core functionality of the JExcel library that allows working with Excel applications, workbooks, worksheets, ranges and cells.

# Embedding a workbook in a Java Swing application.
JExcel provides the JWorkbook component that allows embedding an Excel workbook in a Java Swing application as an ordinary Swing component.

# Handling Excel workbook or worksheet events.
Workbook and Worksheet JExcel classes allow adding listeners for events generated by a workbook or worksheet and event handlers to affect the application behavior.

# Working with native peers.
Native peers are provided to allow you to add custom functionality based on JExcel.
