You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: json.rb
    path of file: ./repos/birdwatcher/lib/birdwatcher/modules/reporting
    
    the code of the file until where you have to start completion: module Birdwatcher
  module Modules
    module Reporting
      class Json < Birdwatcher::Module
        self.meta
    
        def self.info
<<-INFO
The JSON exporter can write the results of an SQL query to a file in JSON format.

#{'IMPORTANT:'.bold} The module does not limit the data returned from the query
to the currently active workspace, the query will need to take that in to
consideration if necessary.
