ℹ️ For Microsoft Office files, ensure they are saved with Office 2019 (Windows) or Office 2016 (Mac) or later versions.

🧩 Support for HTML Inside Files

Some JSON, XLSX, and XLIFF files contain HTML-formatted content, especially when exported from tools like Content Management Systems (CMSs). To ensure this content is translated correctly, Redokun offers the option to treat the text as HTML.

When enabled, Redokun preserves the internal structure of the file and processes the HTML formatting appropriately—extracting only the translatable text while keeping the code intact.

To activate this feature, check the “Treat content as HTML” option when uploading your file.

🛠️ Special Considerations

Adobe InDesign files

If you want to set up the perfect translation workflow when working with Adobe InDesign files, check out our ebook: Make InDesign file translation simple and fast.

Adobe Illustrator Files

To translate .ai , .eps , or .svg files, use Redokun's Illustrator script. For detailed instructions, refer to the Adobe Illustrator Translation Guide.

XLIFF Files

Redokun fully supports XLIFF files generated by Articulate Rise 360 and Articulate Storyline 360. XLIFF files created with other platforms (eg. Intellum Evolve) work out of the box using the generic settings.

HTML Content in Files

For .json , .xlsx , and .xliff files containing HTML content, enable the "Treat content as HTML" option during upload. This ensures proper handling of structured content and formatting.

⚠️ Known Limitations

PowerPoint (.pptx ): Redokun imports slide notes but does not import hidden slides.
InDesign (.idml ):
- Imports all content from all layers and pages, including Parent Pages.
- Does not support translation of endnotes; these remain untranslated.
General: Currently, there is no way to filter or exclude parts of documents or strings that match a specific pattern.

⚠️ XLIFF File Limitations

While Redokun supports the XLIFF 1.2 format, it does not support:

XLIFF 2.0
Translations embedded in the <target> tags of bilingual XLIFF files (Redokun extracts only the source text for translation)
