XLIFF localization

XLIFF (XML Localization Interchange File Format) is the industry-standard format for exchanging localization data between translation tools, content management systems, and service providers. It packages source text, target translations, and contextual data in structured XML that works across platforms. Localazy supports both XLIFF 1.2 and 2.0, so you can translate XLIFF files from virtually any 3rd-party tool without manual conversion.

How Localazy works with XLIFF files

Import XLIFF files through the CLI, API, or web interface; translate using Localazy AI, or human translators on the platform; export completed files ready for any compliant tool.

  • Both versions supported - XLIFF 1.2 and 2.0 handled automatically, including structural variations.
  • Clean translation interface - translators see source and target segments with the optionto collapse the markup inside the string.
  • Context preservation - translation notes from your XLIFF files appear directly in the editor.
  • Vendor-neutral exchange - download XLIFF for any language and import it into any compliant tool.
  • CI/CD automation - integrate XLIFF upload and download into pipelines with the Localazy CLI.

Helpful Localazy features for XLIFF translation

XLIFF cleanup and markup validation

Translators can clean up the clutter inside the strings with a single click of a button to make the text legible and translation less error-prone. Localazy protects any code and markup included inside your XLIFF strings to ensure your files are always valid.

Translation memory across projects

When you work with XLIFF from multiple sources, Localazy’s Translation Memory suggests previously translated segments automatically. Consistency holds across different projects, and repeated translations don’t cost you anything extra.

Sometimes, the XLIFF strings are full of markup tags that clutter the text. In Localazy, these tags are protected during translation and translators can collapse the markup by just clicking a button.

To open XLIFF files, you can use any text editor that supports the format (such as Notepad, Sublime Text, or Notepad++), use online services, or Localazy - the online translation management system explicitly made for working with translation file formats.

Localazy offers a clutter-free way to browse, edit and manage localization files of many formats.

To open XLIFF files using the Localazy interface, sign up, create a new translation project and upload the XLIFF file. You’ll then be able to browse the content of the file in a user-friendly environment.

To translate XLIFF files, you can simply edit the files and translate all content on your own or with the help of machine translation engines such as Google Translate. But this approach is messy, error-prone, and tedious. There is a far better way of doing this.

Translating XLIFF files is simple with Localazy. After signing up for free, create a new translation project and upload your XLIFF file. Head to the Translations tab, add new languages and start translating.

Localazy gives you a clutter-free interface for translating XLIFF files content, with built-in machine translation suggestions and all features a sound translation management system should offer!

To translate XLIFF files automatically, you have two (paid) options:

Localazy reads XLIFF 1.2 and 2.0 files and keeps their structure. You upload the files, translate the content (with the help of Localazy AI), and download the result in the same layout your tool expects.

Create a new Localazy project, set up your style guide and glossary, and choose how your XLIFF content gets translated:

You can also use the Localazy CLI for automated uploads and downloads of XLIFF files from a build pipeline, so translations stay current without manual file handling.

Yes. Format Conversions exports your strings in a different file format than the one you uploaded, for example JSON, PO, Android XML or iOS strings. The reverse also works: upload JSON, download XLIFF.

In the web app, select the format in File Management before downloading. In the CLI, add a conversion section to localazy.json

  1. Create a project and upload the source-language XLIFF file.
  2. Upload the translated files. Localazy reads both <source> and <target> and takes the locale from the file.
  3. Check the strings in the translation table. Localazy links translations to the same unit ids as the source.

If your tool writes different original or id attributes per language, add the ignore_original or ignore_id feature to the upload configuration so the files link correctly. Learn more about how’s Localazy working with XLIFF files in the docs.

Translation memory from another tool can be imported as a TMX file into a separate project and linked via Connected Projects.

Yes. There are three ways, depending on how you want to work.

Invite your vendor into the project. Add the agency’s translators as project members and assign them languages. They translate in the web editor with your style guide, glossary and context screenshots at hand. You see progress and review the work in the same place. No file handover needed.

Exchange XLIFF files with your vendor. Download the XLIFF files from Localazy and send them to the agency. When the translated files come back, upload them as existing translations. Localazy matches them to your strings by unit id.

Order translation from Localazy. Select the languages and strings, and order professional translation directly in the project. Localazy’s localization team manages the work with partner linguists, and the translations arrive in your strings, ready to download.
