I need to show excel and word documents in browser; but the computer has no internet access so I cannot use a cloud-based viewer like Google Docs.
I tried to use ViewerJS but its not working for certain document types such as docx and xlsx
Is there a recommendation for other viewers that can handle these document types?
convert docx or xlsx to pdf using libreoffice as service
Then render that .pdf in viewer.js or just iframe it into your web application
