Description
If you've ever built a family tree in one genealogy program and tried to move it to another, you've probably run into a GEDCOM file — the standard format family-tree software uses to exchange data — that comes back broken, missing dates, or full of duplicate people. GEDCOM Tools is a free set of browser-based fixes for exactly that: it repairs, validates and cleans up these files without you needing to understand the format's often-confusing internal structure.
GEDCOM Tools is a suite of 23 browser-based utilities covering validation, repair, merging, privacy controls, conversion and analysis for GEDCOM files across versions 5.5, 5.5.1 and 7.0. All processing happens locally in the browser — files are never uploaded anywhere — and operations are designed to be non-destructive and reversible, with problems flagged down to the exact record causing them.
💬 Our review
The short version: if you're wrestling with a GEDCOM file that a genealogy program is rejecting or mangling, this free, privacy-preserving toolkit is worth trying before paying for desktop software or trusting an online service with your family data.
Dedicated genealogy platforms like MyHeritage or Family Tree Maker can also validate and clean GEDCOM files, but usually as a side effect of their own import process, tied to their own ecosystem and often requiring an account or subscription. Gramps, the established open-source genealogy manager, offers deep GEDCOM handling but requires installing a full desktop application just to fix one file. GEDCOM Tools' bet is narrower and lighter: 23 focused, single-purpose browser tools, nothing to install, nothing uploaded, and no account required for the core toolset — though some advanced features reportedly sit behind payment, with pricing not fully disclosed. Worth it for a quick, private fix to a specific file problem; less useful if you need an actual ongoing genealogy database, where Gramps or a dedicated platform makes more sense.
