Preview Docx, Doc, xls etc in Browser

Hi, we are currently having Appian developed by a third party, and have come across an issue where we cannot preview any office docs in the browser (Edge/Chrome). We can preview .pdf's. 

Our developer is saying we needs to install some plugins for this functionality to work. Can anyone share their experience of this and offer any recommendations?

We are using 19.2

Thanks

  • I'm not sure the reasoning behind the current restrictions (i seem to remember hearing some mention about security, and i also suspect there's some licensing consideration for the proprietary file types). 

    Anyway, one way I've seen to resolve this for at least some cases, is to use the various PDF conversion utilities available to create temporary PDF-converted copies of whatever file you want to preview on-form, and then display that.  I've successfully used this technique to display HTML files previews on a form, at least.
