Preview MS Office Files with local preview app/generator

Thomas P 1 year ago in Feature requests updated by Vlad R 1 week ago 6

Hi FileRun Dev team,

I would like to suggest an additional way of previewing MS Office document. I already found a somewhat similar discussion of this subject on the Reddit FileRun forum .

Up to my knowledge I can use for MS Office Documents preview:

- Google Docs

- Office Web Viewer/Office356

- OnlyOffice

Google Docs and Office Web Viewer/Office365 are cloud services and therefore bring up data privacy concerns. OnlyOffice offers a community version of the OnlyOffice document server as well as an enterprise version. Even as a docker installation it needs its own database and is a rather big package wit considerable dependencies for only previewing MS Office files.

As a conclusion, I would like to suggest to offer LibreOffice for MS Office files preview. It works for that use case in NextCloud (see https://www.allerstorfer.at/nextcloud-install-preview-generator/ for example) with a rather lightweight, local LibreOffice installation and a preview app in NextCloud. I see the advantage of my suggestion in the absence of data privacy concerns paired with a local and lightweight installation of the preview app.

Perhaps you may consider this feature suggestion for future FileRun versions.

Just for sake of completion I would add that there is also the "Office" plugin, which, opens the file using MS Office, if installed on the user's computer.

ONLYOFFICE DocumentViewer is indeed not a lightweight application.

I am going to check the LibreOffice option and post here shortly after. Thank you for the suggestion.

how is that, we really want to preview office files locally

It seems there is now an option to use a local LibreOffice but I am wondering how I can do this if I am using filerun via Docker?


It is used strictly for thumbnail generation.

oh, I should have read that properly, sorry for the confusion

With the next update, it will be used also for generating full previews for the office documents.
