1. Navigate to Workbench. The ad-hoc pipeline editor opens.

2. Replace the existing content by this pipeline:

   Code Block
   language yaml
   pipeline: - drive.read: path: "person.json"

3. RUN the pipeline and you should see the content of the file person.json as output:

   Code Block
   language json
   { "firstName": "Marissa", "lastName": "Smith", "age": 33 }

   This is because the file is automatically converted from a content object to its the mime type format - which is JSON in this case - and then sent to the client.

4. In order to “see” the content object and not the result, change the pipeline to this:

   Code Block
   language yaml
   pipeline: - drive.read: path: "person.json" - set.body: value: "#{@convert.toJson(body)}"

5. RUN the pipeline and you should see as output the content object with meta information about the file:

   Code Block
   language json
   { "name": "person.json", "created": 1637045518731, "lastUpdated": null, "size": 64, "data": "ewogICJmaXJzdE5hbWUiOiAiTWFyaXNzYSIs...", "mimeType": "application/json" }

...

In case you want to work with the JSON data of a file, the data part of the content object is the interesting thing for you. In order to load this into the body, again use the @convert.toJson() but this time point to the data property:

pipeline:
  - drive.read:
      path: "person.json"
  - set.body:
      value: "#{@convert.toJson(body.data)}"

...

You should see an output similar to this, which transformed the JSON:

"Full name: Marissa Smith"
