* It's best to acquire the file in its original format, such as one of the supported file types above (most commonly, InDesign or Microsoft Word), and translate that file.
** TMX files can be uploaded by managers with sufficient permissions using the Translation Memory Import flow.
Talk to your Customer Success Manager about creating a custom upload template for any of the above file types.
