Obba: A Java Object Handler for Excel

Obba provides a bridge from Excel sheets to Java classes.

With Obba, you can easily build Excel GUIs to Java code.

• Loading of arbitrary jar or class files at runtime through an Excel worksheet function.
• Instantiation of Java objects, storing the object reference under a given object label.
• Invocation of methods on objects referenced by their object handle, storing the handle to the result under a given object label.
• Asynchronous method invocation and tools for synchronization, turning your spreadsheet into a multi-threaded calculation tool.
• Serialization and de-serialization (save Serializable objects to a file, restore them any time later).
• All this though spreadsheet functions, without any additional line of code (no VBA needed, no additional Java code needed).

For a more detailed introduction see the Obba documentation on the Obba homepage.
