What Is XLIFF to JSON?

XLIFF (XML Localization Interchange File Format) is the OASIS-standard XML format for exchanging localization data between tools and vendors. Converting XLIFF to JSON allows developers to integrate translation content directly into web applications without XML parsing overhead.

This is used for:

  • Localization Workflows: Extracting translation units from XLIFF files exported by CAT tools like SDL Trados, memoQ, or Smartling into simple JSON objects.
  • Web App Integration: Feeding XLIFF-sourced translations into JavaScript i18n libraries that consume JSON-formatted key-value pairs.
  • Data Migration: Converting legacy XLIFF archives into JSON for modern cloud-based translation management systems.

How to Use XLIFF to JSON Online

  1. Paste your XLIFF XML: Copy your entire XLIFF 1.2 document, including the XML declaration and all trans-unit elements with source and target values.
  2. Click Convert: Press the Convert to JSON button to parse the XML structure and extract all translation pairs into a clean JSON object.
  3. Copy or download: Copy the resulting JSON to your clipboard or download it for use in your application.

Real-World Examples

Enterprise localization teams frequently use XLIFF as the exchange format between translation vendors and engineering teams. After translations are completed in a CAT tool, the resulting XLIFF files can be converted to JSON for direct integration into single-page applications built with React, Angular, or Vue.
