JExcelApi is an open source and mature Java API enabling developers to read, write, and modifiy Excel spreadsheets dynamically.
Now Java developers can read Excel spreadsheets, modify them with a convenient and simple API, and write the changes to any output stream (e.g. disk, HTTP, database, or any socket).
Any operating system which can run a Java virtual machine (i.e., not just Windows) can both process and deliver Excel spreadsheets. Because it is Java, the API can be invoked from within a servlet, thus giving access to Excel spreadsheets over internet and intranet web applications.
Here are some key features of "JExcelApi":
· Reads data from Excel 95, 97, 2000, XP, and 2003 workbooks
· Reads and writes formulas (Excel 97 and later only)
· Generates spreadsheets in Excel 2000 format
· Supports font, number and date formatting
· Supports shading, bordering, and coloring of cells
· Modifies existing worksheets
· Is internationalized, enabling processing in almost any locale, country, language, or character encoding (formulas are currently only supported in English, French, Spanish, and German, but more can be added if translated)
· Supports copying of charts
· Supports insertion and copying of images into spreadsheets
· Supports logging with Jakarta Commons Logging, log4j, JDK 1.4 Logger, etc
