This is a good place to start, by seeing exactly which extensions are supported, and what input types they map to.

Next step would be to look at the list of supported inputs, and exclude those extensions which map to an unsupported input format. https://pandoc.org/MANUAL.html#option--from.

I've implemented the above -- certain files are excluded based on extension, while I provide the input format for some extensions which Pandoc doesn't handle automatically.
