GEDCOM Import and Export Guide should help a visitor accomplish a specific family-history task, not merely define a term. Move genealogy data between compatible applications with fewer surprises by understanding what transfers, what may not, and how to verify results. This page is written for people who want practical guidance they can use immediately. It explains what to do, why it matters, where mistakes usually happen, and how the page connects with the wider Family-Trees-Maker.com toolkit. The primary keyword, GEDCOM import export, is used naturally throughout the page without turning the copy into repetitive search-engine text.
The most useful version of a GEDCOM import export combines a simple starting point with enough depth for the project to grow. Beginners should be able to take the first action without learning specialist terminology, while experienced researchers should be able to preserve context, correct mistakes, and move data when needed. The following capabilities and practices are the foundation of this page:
These points matter because family history changes as new information appears. A GEDCOM import export that works only for the first ten names quickly becomes frustrating when relatives add corrections, a GEDCOM file is imported, or the chart needs to be printed at a larger scale. Build for revision from the start rather than treating the first version as final.
A strong GEDCOM import export experience starts with a clear purpose. Export a fresh backup before migration. This sounds simple, but it prevents a common problem: users often add information because a field is available rather than because it helps answer a family-history question. Decide what the page, chart, or research task needs to accomplish, then include the information that supports that goal. When details are uncertain, mark them as estimates or leave them open for further research instead of filling gaps with convenient guesses.
A practical way to use this advice is to create a small test case before applying it to an entire family project. For example, take one household or one three-generation branch and check how export a fresh backup before migration affects names, relationships, dates, privacy, and output. If the result remains clear after printing, exporting, or sharing it with another person, the same method can usually be extended to a larger GEDCOM import export project. If it becomes confusing at a small scale, solve the structure first rather than multiplying the problem across hundreds of profiles.
In practical use, note the GEDCOM version and source application. Treat this as part of the workflow rather than an optional extra. A GEDCOM import export can become confusing when relationships, labels, and source notes are handled inconsistently. Use the same naming conventions across branches, keep date formats predictable, and review how each change affects connected relatives. This is especially important in families with repeated names, multiple marriages, adoption, step relationships, or people who moved between places with similar names.

One useful rule for working with a GEDCOM import export is to make each action reversible whenever possible. When you expect some custom fields to map differently, keep an export or backup before a large change and record why the change was made if the evidence is not obvious. That gives future you – or another relative helping with the project – enough context to understand the decision. The objective is not to make the tree look complete at any cost; it is to make the information understandable, maintainable, and increasingly accurate over time.

Users often overlook a practical detail: check citations, notes, media links and special relationships. On a small family project the impact may be minor, but on a larger tree it affects readability, accuracy, and portability. Build the habit early. A well-organized GEDCOM import export should still make sense months later when you return to it, when a relative proposes a correction, or when you move the data to another format. Clear labels, cautious edits, and simple backups turn a one-time chart into a useful family-history record.

The best way to apply this is to test it with a real branch of the family. Compare record counts before and after import. Then review the result from the perspective of someone who did not enter the data. Can that person identify the relationship? Can they tell which dates are exact and which are approximate? Can they understand why a parent-child connection was made? A GEDCOM import export should communicate the structure of the family without requiring the creator to explain every box and line in person.

For trustworthy results, keep the original program data until verification is complete. Avoid treating the GEDCOM import export as an authority that automatically makes imported or entered data true. Tools organize information; they do not replace evidence. If a relationship comes from an online tree, family story, index, or automated hint, record that context and look for stronger supporting sources when the conclusion matters. This keeps the project useful for both casual family sharing and more serious genealogy research.

A tree imports 1,240 people but only 1,198 appear, prompting a check for privacy filters and unsupported records.
Why this matters: the example shows how a GEDCOM import export should support a real decision instead of simply producing a visually complete result. The useful outcome is a tree, file, chart, or research note that another person can understand and that can be corrected later if stronger evidence appears.
Media links point to files on the old computer, so images are migrated separately.

Situation | Recommended approach | Reason |
Small beginner project | Start with 2-4 generations and essential facts | Easy to verify and revise |
Growing genealogy project | Use profiles, notes, sources and regular exports | Keeps context as the tree expands |
School or presentation use | Choose a simple visual layout and readable labels | Prioritizes clarity over research detail |
Family reunion | Use descendant-focused structure and privacy review | Helps relatives see branch connections safely |
Long-term research | Keep structured backups and evidence notes | Reduces data loss and unsupported conclusions |
Good family-history work separates what is known from what is assumed. A name match by itself is rarely enough to prove identity, especially when common names repeat within the same county or even within one family. Record the evidence that supports each important relationship, note conflicts instead of hiding them, and keep uncertain conclusions clearly labeled. This approach makes the tree easier to correct later and helps relatives understand why a connection was made.
Privacy deserves the same attention as accuracy. Information about living people can include exact birth dates, family relationships, photographs, addresses, contact details, and private events. Before publishing or sharing a tree, review what another person actually needs to see. A printable reunion chart may need names and relationship lines, for example, but it usually does not need full birth dates, addresses, or private notes.
Data portability is another practical issue that simple GEDCOM import export pages often ignore. If a project becomes important, keep backups in more than one useful format. A printable PDF preserves presentation, while a structured genealogy export such as GEDCOM preserves much of the underlying family data. These formats solve different problems, so one should not be treated as a substitute for the other.
A good GEDCOM import export workflow makes these mistakes easier to detect. Build slowly enough to review each branch, use notes for uncertainty, and separate the research database from the simplified chart you may print or share. A family tree does not become more trustworthy merely because it contains more people; confidence comes from clear relationships, evidence, and transparent uncertainty.
This workflow works because it separates collection, verification, presentation, and sharing. Those tasks often get mixed together. Someone designing an attractive GEDCOM import export may be tempted to fill a missing branch simply to balance the chart, while someone researching records may collect too much detail for a one-page printout. Keeping the purpose clear produces a better result in both cases.
These habits are deliberately simple. They do not require advanced genealogy training, but they make a GEDCOM import export more reliable and easier to maintain. The main principle is to preserve context: who a person is, how they connect, what evidence supports the connection, and which details are still uncertain.
Start with the purpose of the page and the relatives you already know. A GEDCOM import export is most useful when it grows from verified close relationships rather than from a large number of unverified names.
You can work with incomplete information. Leave unknown fields blank, use an approximate year when justified, and add a research note so the gap is visible rather than hidden.
For important relationships, compare more than one clue. Names, dates, places, spouses, parents, children and original records together are stronger than a single matching name.
For sharing, remove unnecessary details about living people. A family member may need to see relationship lines without seeing exact birth dates, private notes, addresses or contact information.
For long-term projects, keep both a visual export and a structured data backup where available. They solve different needs: one preserves presentation and the other preserves editable genealogy data.
When the project becomes too large for one chart, split it by branch, generation, or research question. The underlying tree can remain comprehensive even when each visual view is intentionally focused.
A useful GEDCOM import export should make the next action obvious while protecting the quality of the underlying family history. Start with known relatives, keep uncertain information visible, document important evidence, protect living people, and maintain backups as the project grows. Whether the visitor is making a school chart, researching ancestors, preparing a reunion display, or preserving a multi-generation family archive, the page should help them leave with a clearer and more reliable result than they had when they arrived.
