Welcome to the PicoXLSX4j wiki!

PicoXLSX is a port of PicoXLSX for C#. It is a small Java library to create Microsoft Excel files (XLSX for Office 2007 or newer) in an easy and native way. This means:

• No need for an installation of Microsoft Office
• No need for Office interop/DCOM or other bridging libraries
• No need for 3rd party libraries
• Pure usage of standard JRE

See the Change Log for recent updates.

PicoXLSX4j was created with Java 8 and is fully compatible with Java 7
The only requirements for development are a current JDK to develop and JRE to run.

Simply place the PicoXLSX4j.jar into the lib folder of your project and create a library reference to it in your IDE.

Place all .java files from the PicoXLSX4j source folder into your project. The folder structure defines the packages. Please use refactoring if you want to relocate the files.

Add the following information to your POM file within the <dependencies> tag:

<dependency>
    <groupId>ch.rabanti</groupId>
    <artifactId>picoxlsx4j</artifactId>
    <version>VERSION NUMBER</version>
</dependency>

Important: The VERSION NUMBER must be defined (e.g. 2.3.1). Please see the version number of Maven Central or check the Change Log for the most recent version. The keywords LATEST and RELEASE are only valid in Maven 2, not 3 and newer.
