Overview of document translation in Microsoft Syntex
Note
Through June 2025, you can try out a limited amount of document translation and other selected Syntex services at no cost if you have pay-as-you-go billing set up. For information and limitations, see Try out Microsoft Syntex and explore its services.
Microsoft Syntex lets you easily create a translated copy of a selected file or a set of files in a SharePoint document library. You can translate a file in one language or up to 10 language at a time, while preserving the original format and structure of the file. Translation is available for all supported languages and dialects.
This feature lets you translate files of different types either manually or automatically by creating a rule.
You can also use the translation feature for translating video transcripts and closed captioning files. For more information, see Transcript translations in Stream for SharePoint.
