-Gotenberg provides the endpoint `/convert/office` for Office documents conversions.
-
-It accepts `POST` requests with a `multipart/form-data` Content-Type.
-
-## Basic
-
-You may send one or more Office documents. Following file extensions are accepted:
-
-* `.doc`
-* `.docx`
-* `.odt`
-* `.xls`
-* `.xlsx`
-* `.ods`
-* `.ppt`
-* `.pptx`
-* `.odp`
-
-All files will be merged into a single resulting PDF.
-
-> **Attention:** currently, `unoconv` cannot perform concurrent conversions.
-> That's why for Office conversions, the API does only one conversion at a time.
-> See the [scalability section](#scalability) to find how to mitigate this issue.
