I need to send a JSON file to a team to upload into redcap and they are requiring the data be formatted in a specific way and I'm wondering if there is an option to get proc JSON to perform this task? The in statement we're using in the testing stage is below but I have many observations and many more variables to add in production.

in='{"projectId":"999", "data": "[{\"record_id\", \"test91\"},{\"record_id\": \"test57\"}]","serverName":"EXTERNAL"}'
