You could maybe do it with flex.io and connecting to the data using a Skuid data source.
https://www.flex.io/docs/tutorials/create-an-api-endpoint-from-a-csv-file-in-a-cloud-storage-service

Not CSV - but we convert CSV’s to JSON files all the time and store them in Github - and use a REST connector to get at them. Works great. 

On Skuid platform you can store the JSON file in the 'FILES" section of the admin and get at them there.  All the platform sample pages at https://portal.skuidsite.com/designsystem/samplepages  are built this way.  You can install any of these in your own skuid platform instance and see the magic.
