Supported File Formats

LILT supports the import and export of a wide range of file types to make your translation workflow as streamlined as possible. All supported formats are listed in the tables below. By default, documents are exported in the same format they were uploaded. Exporting to plain text and XLIFF 1.2 is also available (see the Document Downloads section of the Document Actions article). All translated and confirmed segments can also be exported in TMX format for each Data Source. Supported formats are TMX and SDLTM.

For formats supported by the Enterprise portal please refer to the link.

Desktop publishing formats

Extension	Format
DOCM, DOCX, DOTM, DOTX, POTM, POTX, PPSM, PPSX, PPTM, PPTX, XLSM, XLSX, XLTM, XLTX, VSDM, VSDX	Microsoft Office 2007+
ODG, ODP, ODS, ODT, OTG, OTP, OTS, OTT	OpenOffice / LibreOffice
PDF	PDF (import only!)
IDML, MIF	Adobe InDesign, FrameMaker

The following formats do not support export in their original format and thus only support export to text or XLIFF:

Microsoft Office legacy file formats (DOC, XLS, and PPT). Note: The import of Microsoft Office legacy file formats is only available via the API.
PDF files. Note that PDF files sometimes contain hard line breaks, which can result in unfavorable segmentation. We suggest to either use the original file format (if available) or convert PDF to Word (there are lots of very good free tools for this). The Word document can be translated, exported, and then saved as a PDF again. In case you already started or even finished translating a PDF but require the original formatting, you can convert the PDF to Word and upload the Word document to the same project. Exact matches from your PDF translation will then be autopropagated to this new document within the LILT Project.
