What is an XLIFF file? An XLIFF file is a localization file that stores language translation data in the XML Localization Interchange File Format (XLIFF) standard. It contains the original text from a software program or document, along with its translations into one or more target languages. The Organization for the Advancement of Structured Information Standards (OASIS) developed the XLIFF format to make it easier to exchange translation information among different localization tools.
More Information Software developers and translators use XLIFF files to manage translation in applications, websites, and documentation. The format maintains the source text separate from the translated text, helping prevent errors and making it easier to update or reuse translations.
