VGedX Online: The GEDCOM Validator
VGedX now supports validating GEDCOM 5.5, 5.5.1 and 5.6 files online.
VGedX will flag parsing errors, length and occurence warnings. VGedX does not validate data field content with the exception of date fields. You can head on over to the Bonkers
page afterwards if you want to perfom a sanity check of your file.
Options are provided here for ignoring common warnings. Processing of your file can take several minutes, depending on the size and complexity of your database, so please be patient.
