  • Supports multiple languages and cultures.[9]
    • Full Unicode support.
    • Relationship calculators.[10] Some languages have relationship terminology with no proper translation to other languages. Gramps deals with this by allowing for language specific relationship calculators.
  • Generates reports in multiple formats, including .odt, LaTeX, .pdf, .rtf, .html, and .txt.
  • Gramps is easily extended via plugins called Gramplets. A Gramplet is a view of data that either changes dynamically during the running of Gramps, or provides interactivity to your genealogical data.[11]

Container forGramps XML and referenced media

The core export file format of Gramps is named Gramps XML and uses the file extension .gramps. It is extended from XML. Gramps XML is a free format. Gramps usually compresses Gramps XML files with gzip.[14] The file format Portable Gramps XML Package uses the extension .gpkg and is currently a .tar.gz archive including Gramps XML together with all referenced media. The user may rename the file extension .gramps to .gz for editing the content of the genealogy document with a text editor. Internally, Gramps uses SQLite as the default database backend, with other databases available as plugins.[15]

Gramps can import from the following formats:[16] Gramps XML, Gramps Package (Portable Gramps XML), Gramps 2.x .grdb (older versions Gramps), GEDCOM, CSV.

Gramps supports exporting data in the following formats: Gramps XML, Gramps Package (Portable Gramps XML), GEDCOM, GeneWeb's GW format,[17] Web Family Tree (.WFT) format,[18] vCard, vCalendar, CSV.

Programs that support Gramps XML

  • PhpGedView (version 4.1 and up) supports[19] output to Gramps XML.
  • The script tmg2gramps by Anne Jessel converts The Master Genealogist v6 genealogy software datafile to a Gramps v2.2.6 XML.
  • The Gramps PHP component JoomlaGen for Joomla uses an upload of the GRAMPS XML database export to show genealogical information and overviews. JoomlaGen is compatible with GRAMPS 3.3.0.[20]


Gramps is available in 40 languages[8] (December 2014).

Gramps also has two special use sub-translation languages:

  • Animal pedigree which allows to keep track of the pedigree and breed of animals[21]
  • Same gender/sex which makes using Gramps far more intuitive when dealing with a same gender family.[22]
