Once the check is complete, a list of potential compatibility issues is displayed.  You can right click on any issues found to get help on how to fix the error or open the file in a text editor (see Options).  You can limit the display of duplicate issues by checking "Show fewer duplicates".

Results can be filtered by typing in the filter box.  You can filter on severity (error, warning, information, recommendation), code (e.g. W101, E102), line number and description.  You can also use the column filters to hide specific severities or codes.

Results can be sorted by clicking on the column headings.  Hold the ctrl key whilst clicking a column heading to clear a sort or hold the shift key to sort on multiple columns at the same time.

Supported GEDCOM Versions

Files are validated according to the version specified in the GEDCOM header, unless the file was produced by an application which is known to report the incorrect GEDCOM version in the header.

Two validation modes are possible.  "Best practice" mode is the default and takes into account a number of inconsistencies and errors in the GEDCOM specifications which developers get wrong.  Developers are well advised to ensure that their GEDCOM writers produce GEDCOM files which pass the best practice mode without generating any warnings or recommendations.  A second "Standards only" mode is for completeness only and validates against the GEDCOM specifications as written, including any errors.

The following table lists the support status for different versions of the GEDCOM specifications.

GEDCOM Version Status
1.0, 2.0, 2.1, 3.0, 4.0, 5.0, 5.1, 5.2, 5.3, 5.4 Obsolete and not supported
5.5, 5.5.1 and 5.6 Supported
