Cognite Data Fusion/InField/Remote: MS Office document viewing

We assumed that viewing documents from MS OFFICE suite would have been easy access from the Cognite Ecosystem but it appears they are a challenge. It is important that we can seamlessly view the files including excel, word and powerpoints in the browser via CDF or Cognite app without it being a PDF version. Converting Excel into PDF does not make sense. There are several ways embedded browser viewing can be enabled for this without asking users to download it. 

This is mostly important for tablets and hand held devices where people may not have MS OFFICE apps on the devices and we do not want to download documents on the devices.
