How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a GEDCOM from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your XLSX the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert GEDCOM → XLSX

What this conversion is actually for

GEDCOM is a genealogy interchange format no spreadsheet reads natively. Converting to XLSX gives you one row per person with names, dates, places, and family links, so you can sort your tree by birth year, spot gaps, or share it with relatives who only have Excel.

A real example

You exported a 1,200-person tree from Ancestry as .ged and want to find everyone born before 1850 with no death date. Convert to XLSX, filter the birth and death columns, and the gaps are obvious.

Troubleshooting

Family relationships look like ID codes.

familyAsChild and familyAsSpouse hold GEDCOM family IDs on purpose so you can join people back to households. Sort or filter by those columns to group a family.

Accented or non-Latin names look wrong.

Older GEDCOM files use ANSEL or a non-UTF-8 encoding. Re-export as GEDCOM 5.5.1 with UTF-8 from your genealogy software, then reconvert.

About GEDCOM and XLSX

GEDCOM, Genealogical Data Communication

GEDCOM is the universal interchange format for family-tree data. The current spec is GEDCOM 7.0 (2021) but most genealogy software still emits GEDCOM 5.5.1 (2019) for compatibility. Plain-text hierarchical records: 0-level lines define individuals (INDI) and families (FAM); deeper levels (1, 2, 3...) attach attributes like names, dates, and places. Every major genealogy app reads and writes GEDCOM.

How to open

Ancestry, MyHeritage, FamilySearch, RootsMagic, Family Tree Maker, Gramps, MacFamilyTree. Plain text in any editor.

XLSX, Microsoft Excel Spreadsheet

XLSX is the spreadsheet format Excel has used since 2007, like DOCX, it's a zip containing XML for cells, formulas, formatting, and embedded objects. Replaces the older binary .xls format. Read and written by Excel, Google Sheets, Apple Numbers, and LibreOffice Calc, with high fidelity for standard cell data and reasonable fidelity for complex formulas and pivot tables.

How to open

Microsoft Excel, Google Sheets, Apple Numbers, LibreOffice Calc. CSV is a more portable format if you only need the raw cell values.

FAQ

Common questions

Is this GEDCOM → XLSX converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert GEDCOM to XLSX?

Family tree interchange between genealogy programs. Spreadsheets with formulas, formatting, multiple sheets. The most common reason to convert is compatibility, XLSX works in places where GEDCOM doesn't, or vice versa.

How do I open a GEDCOM file in the first place?

Ancestry, MyHeritage, FamilySearch, RootsMagic, Family Tree Maker, Gramps, MacFamilyTree. Plain text in any editor.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
