Welcome

gedcom4j is an open-source, free-to-use Java library for loading (parsing) and saving genealogy data. Using gedcom4j, you can write a Java program to load data from a GEDCOM 5.5 or 5.5.1 file into a Java data structure for your examination and manipulation, and you can also write GEDCOM files out from the same data model, with or without having already loaded a file.

Please note that gedcom4j is not an application. It is a library (jar file) that can parse, manipulate, and write genealogy data using the GEDCOM format in your own Java programs.
