A new version of Obba has been released: Obba Version 2.2.15.

Obba provides a bridge from spreadsheets (Excel or OpenOffice) to Java classes via worksheet functions (UDFs), without the need to write a single line of code. With Obba, you can easily build spreadsheet GUIs to Java classes. Obba is available for Excel and OpenOffice and Obba sheets may be migrated from Excel to OpenOffice or vice versa.
