Utility ~ GedPad Editor
GedPad is a freeware line-editor for GEDCOM files, and understands the GEDCOM standard syntax.
This small utility program can read and do global search and replace on a GEDCOM file, while retaining its consistency. Can be handy when replacing CHR with BAPT fields, or for changing UDFs from other Family History programs.
