If you’ve ever built a family tree online, there’s a good chance you’ve wondered what would happen if you wanted to move it, back it up, or share it with someone else. That’s exactly where GEDCOM comes in, and once you understand it, a lot of genealogy starts to feel much less fragile.

Whether you use Ancestry, MyHeritage, FamilySearch, Findmypast, or desktop genealogy software, GEDCOM is the format that helps keep your research portable.

What is a GEDCOM file?

A GEDCOM file is the standard file format used to store and transfer genealogy data.

GEDCOM stands for Genealogical Data Communication.

In simple terms, it’s the format that allows family tree data to move between different genealogy websites and software programs. Instead of retyping names, dates, places, relationships, and notes by hand, you can export your work as a GEDCOM file and import it into another compatible system.

A GEDCOM file can include:

• Names

• Family relationships

• Birth, marriage, and death details

• Dates and places

• Notes

• Sources and citations

• Links between individuals and family units

It may not look impressive on the surface, but it plays a crucial role in preserving the structure of your family history research.

Why GEDCOM matters

One of the quiet risks in genealogy is becoming too dependent on a single platform.

Websites likeAncestry, MyHeritage, FamilySearch, and Findmypastare incredibly useful for research, hints, and record access. But your family tree is more than a feature inside someone else’s platform. It represents years of work, decisions, corrections, and discoveries.

GEDCOM matters because it helps you keep control of that work.

With a GEDCOM file, you can:

• Back up your tree outside a single service

• Move your research between platforms and software

• Share your data with relatives, researchers, or clients

• Preserve your core family history in a widely recognised format

Without GEDCOM, switching systems can become messy, incomplete, or heavily manual. With it, your research remains portable.

What does a GEDCOM file actually contain?

A GEDCOM file is a structured text file. It does not look like a chart or visual family tree when opened directly. Instead, it stores genealogical information line by line in a format that software can interpret.

For example:

text

0 @I1@ INDI
1 NAME John /Smith/
1 BIRT
2 DATE 1 JAN 1900

This tells a genealogy program that the file contains an individual record, gives that person’s name, and records a birth event with a date.

You do not need to edit GEDCOM files manually, but understanding that they are structured text can make the whole idea feel much less mysterious.

Why GEDCOM is still essential in modern genealogy

GEDCOM has been around for a long time, but it remains one of the most important standards in family history.

That is because it solves a practical problem that every genealogist eventually faces: how to move data without losing the essentials.

Whether you are:

• downloading your tree from Ancestry

• moving research into desktop software

• sharing a file with a cousin

• transferring a project from MyHeritage to Findmypast

• maintaining your own archive separate from FamilySearch

GEDCOM is usually the format that makes that possible.

It is not perfect, but it remains the most widely supported way to transfer core genealogy data.

GEDCOM 5.5.1, GEDCOM 7.0, and GEDCOM X

Not all GEDCOM files are exactly the same.

GEDCOM 5.5.1

GEDCOM 5.5.1 is still the most widely used version because it works with a broad range of genealogy websites and desktop programs. If your main concern is compatibility, this is often the safest option.

GEDCOM 7.0

GEDCOM 7.0 is a newer version of the standard. It offers several improvements, including:

• Better support for multimedia

• Improved character encoding for international names and places

• A cleaner, more modern structure

The challenge is that adoption is still uneven. Some tools support it well, while others still rely mainly on 5.5.1.

GEDCOM X

You may also come across GEDCOM X, particularly in FamilySearch-related contexts. GEDCOM X was developed by FamilySearch as a separate, more modern data model for family history information.

It is worth knowing about, but it is not the same as GEDCOM 7.0, and it has not replaced traditional GEDCOM for everyday file exchange. For most users, standard GEDCOM remains the format that matters most when moving tree data between systems.

What GEDCOM files do well — and where they fall short

GEDCOM is very good at preserving the core structure of a family tree.

It usually transfers well:

• Individuals

• Families and relationships

• Key life events

• Dates and places

• Notes

• Source citations

However, some things may not transfer cleanly between platforms such as Ancestry, MyHeritage, Findmypast, FamilySearch-connected tools, and desktop software.

These can include:

• Complex note formatting

• Media files and image links

• Custom fields used by specific software

• Colour coding, charts, and layout settings

• Some source templates or proprietary features

That does not mean GEDCOM has failed. It simply means the file format is designed to preserve the research itself, not every platform-specific feature layered on top of it.

How to export a GEDCOM from Ancestry

If you want to download your tree fromAncestry, the usual process is:

1. Sign in to Ancestry

2. Open the tree you want to export

3. Go toTree Settings

4. Find theExport treeoption

5. Wait while the file is prepared

6. ClickDownload your GEDCOM file

Keep in mind that the GEDCOM typically includes your tree data, but not necessarily every attached media file.

How to export a GEDCOM from MyHeritage

To export a GEDCOM fromMyHeritage:

1. Sign in to MyHeritage

2. Open your family tree

3. Go to the relevantsite or tree settings

4. ChooseExport to GEDCOM

5. Request the export

6. Download the file when it is ready

As with most platforms, your exported GEDCOM will usually capture the main genealogical data better than any media attachments or platform-specific formatting.

How to export a GEDCOM from Findmypast

If you useFindmypast, the process can vary slightly depending on the current tree interface and features available.

A typical approach is:

1. Sign in to Findmypast

2. Open your family tree

3. Go to the tree menu or settings section

4. Look for anexportordownload GEDCOMoption

5. Follow the prompts to generate the file

If you do not see an export option, it is worth checking Findmypast’s latest help guidance, as interface details can change over time.

As with Ancestry and MyHeritage, the GEDCOM should be treated as a transfer and backup format for your tree data, not a guaranteed full copy of every image, record attachment, or custom feature.

What to know about FamilySearch

FamilySearchworks differently from Ancestry, MyHeritage, and Findmypast because its main Family Tree is collaborative and shared rather than a separate private tree in the same sense.

That meansFamilySearch does not usually offer a straightforward GEDCOM export of the shared Family Tree.

In practice, many genealogists use FamilySearch as part of their research process while maintaining a personal master tree in desktop software or another platform. They then export their GEDCOM from that personal tree when they need a backup or transfer file.

So if you use FamilySearch regularly, the safest approach is not to rely on it as your only copy of your tree.

How to open a GEDCOM file

To open a GEDCOM file, you generally need genealogy software or an online platform that supports GEDCOM import.

Common options include:

• Desktop genealogy programs

• Online family tree services

• GEDCOM viewers

• A plain text editor, if you simply want to inspect the raw file

If you open it in a text editor, it will look like code rather than a family tree. That is normal.

How to validate a GEDCOM file

Before importing or sharing a GEDCOM file, it is a good idea to validate it.

Validation checks whether the file follows GEDCOM structure correctly and helps catch errors early.

Two useful options are:

• Chronoplex GEDCOM Validator

• GEDCOM.io tools and reference resources

Validation can help identify:

• Structural errors

• Invalid or unsupported tags

• Broken links between records

• Character encoding problems

This is especially useful if the file has been edited manually, exported from older software, or moved through multiple systems.

Privacy matters when sharing GEDCOM files

A GEDCOM file can contain information about living individuals, and this is one of the most important things to remember before sharing one.

Depending on the file and software used, it may include:

• Full names

• Birth dates

• Marriage details

• Locations

• Notes about family members

Before sending a GEDCOM to someone else or uploading it online:

• Review what the file contains

• Remove or privatise living individuals where possible

• Check whether your software offers privacy options during export

• Be cautious about public uploads and casual file sharing

Family history research is personal, and protecting living relatives should always be part of responsible genealogy practice.

Best practices for working with GEDCOM

A few habits can make GEDCOM much more reliable and useful.

Export regular backups

Do not rely entirely on Ancestry, MyHeritage, Findmypast, FamilySearch-connected tools, or any single software program as the only place your tree exists. Export a backup regularly.

Be consistent with dates and places

Clear, consistent data improves how your tree behaves when moved between systems.

Review duplicates after import

Merging trees can create duplicate people surprisingly easily. Always review imported data carefully.

Keep your sources

Sources make your work stronger, more credible, and easier to verify later.

Validate before sharing

A quick validation check can prevent unnecessary problems.

Test before making a full move

If you are transferring a large tree from one system to another, try a test import first so you can see what transfers well and what needs tidying up.

GEDCOM and collaboration

One of GEDCOM’s most useful strengths is how well it supports collaboration.

Instead of sharing screenshots, printouts, or fragments of a tree, you can share a structured dataset. That makes it easier to:

• compare findings

• review evidence

• merge research

• spot differences

• build on each other’s work

Whether you are collaborating with relatives, clients, or fellow researchers, GEDCOM gives you a more reliable starting point.

Final thoughts

GEDCOM may not be the most exciting part of family history, but it’s one of the most useful. It helps you keep hold of your work, share it more easily, and make sure years of research don’t get stuck in one place.

For anyone using Ancestry, MyHeritage, Findmypast, FamilySearch, or genealogy software, understanding GEDCOM is part of protecting the work you have already done — and making sure it remains useful in the future.
