Pick File Viewer if…
File Viewer may suit teams building browser-based file previews into web applications, especially when they want self-hosted or offline deployment. It is for viewing rather than editing files.
Pick Universal File Opener if…
It suits people who want to read supported files offline on Android or Windows, including users who need previews or in-file search. Android users who need spreadsheet editing should note that it does not provide full workbook recalculation.
