Frequently Asked Questions

What is XLIFF localization?

XLIFF localization helps you translate content while keeping all the formatting intact. Think of XLIFF as a smart container that separates the source text you need to translate from the technical formatting, making the whole process cleaner and more efficient. It separates translatable text into segments while preserving formatting through inline elements and tags.

How can learning and development teams benefit from XLIFF localization?

AI is transforming corporate training by offering innovative solutions to enhance learning experiences and personalize training programs.[1] Generative AI directly supports L&D teams by being poised to revolutionize educational content creation, promising resources that are both high-quality and cost-effective.[2]

Translation tools like Smartcat’s Learning Content Agent automate course development by drafting, structuring, and formatting training content quickly, freeing L&D teams to focus on strategy and learner engagement.

These AI Agents translate and localize learning materials simultaneously as they are created, ensuring consistent, accurate, and on-brand training ready for every market from day one.

How does Smartcat handle the localization of XLIFF files?

Smartcat's Software Localization Agent handles your XLIFF files automatically, preserving all formatting so you can focus on creating great content rather than managing technical details. Our AI agents learn from every edit, using translation memory to continuously improve quality and maintain formatting across all your projects.

Can I use an XLIFF converter with Smartcat?

Smartcat’s built-in XLIFF conversion capabilities work for 80+ file formats, eliminating the need for separate XLIFF converters. Our platform automatically handles conversion to and from XLIFF format while preserving all structural elements and formatting.

What are the differences between XLIFF 1.2 and XLIFF 2.0?

XLIFF 2.0 introduces a more modular architecture with a streamlined core and specialized extensions for advanced functionality. It offers improved handling of inline elements, better metadata support, and enhanced validation capabilities compared to XLIFF 1.2.

What is XLIFF extraction and how does it work?

XLIFF extraction is the process of pulling translatable content from source files (like HTML, XML, or DOCX) into the XLIFF format. Smartcat's extraction tools automatically identify translatable text, convert it to XLIFF segments, and preserve formatting as inline elements.

What is XLIFF validation?

XLIFF validation verifies that files comply with the OASIS XLIFF specification and contain properly formed XML. Smartcat automatically validates XLIFF files during import, identifying potential issues with structure, namespaces, or inline elements before translation begins.

Is my XLIFF content secure during translation?

Smartcat employs enterprise-grade security protocols including end-to-end encryption to protect your XLIFF files. Our platform is SOC 2 Type II compliant, ensuring your content remains confidential throughout the localization process.

How does XLIFF merging work?

XLIFF merging reintegrates translated content from XLIFF files back into the original file format. Smartcat's merging process preserves all formatting, replaces source-language content with target language translations, and ensures the final output matches the original structure exactly.

What are XLIFF segments and how are they handled?

XLIFF segments are individual translatable units within an XLIFF file, typically sentences or phrases. Smartcat's platform preserves segment boundaries, maintains context between segments, and tracks translation state (translated, reviewed, approved) for each segment.

How do you handle inline elements in XLIFF?

Inline elements in XLIFF represent formatting, placeholders, or other non-translatable content within segments. Smartcat's XLIFF editor protects these target elements during translation, making them visible but non-editable to ensure they remain intact throughout the process.
