This would be awesome! What you probably want is to hook into the preview
stuff:

http://docs.ckan.org/en/ckan-2.0/extensions.html#ckan.plugins.interfaces.IResourcePreview

As examples here are some existing ones:

PDF: https://github.com/okfn/ckan/tree/master/ckanext/pdfpreview
Text (including JSON):
https://github.com/okfn/ckan/tree/master/ckanext/textpreview
GeoJSON:
https://github.com/okfn/ckanext-spatial/blob/master/ckanext/spatial/nongeos_plugin.py#L43

I've also asked a question on stackoverflow to see if people have further
tips:
