Import data from different formats

Supported formats by the Cocoa Browser are:

• CSV
• XLSX

Not sure if XLSX really makes sense and if there are any 3rd party node modules to parse it, but JSON should definitely be added as well.

Could we also import from a Realm file?

Hey - looks like you forgot to add a T-* label - could you please add one (if you have access to add labels)?
