Hi
Is this possible? I have tried to use Pandoc as the external renderer (as is the case for .docx files), but when I try to view the file, I get a 500 error and a Pandoc 21 error (which says that it doesn’t know what xlsx files are!). Here’s what I added to Gitea’s app.ini 
[markup.xlsx]
ENABLED = true
FILE_EXTENSIONS = .xlsx
RENDER_COMMAND = pandoc --from xlsx --to html5 --embed-resources --standalone –template /usr/share/pandoc/data/templates/default.html5
IS_INPUT_FILE = false
So, have I made an error with this render command, or will Gitea not support the rendering? Any help gratefully received!
