Retrieving Data from Rasa Open Source into a database

I want the data column which is text to be passed as JSON ,is there any way to do that?

Not sure I understand the question. The data column in your screen shot is json not text. Passed to where via what mechanism?

You can configure the Rasa event broker and all events will be passed to the broker (RabbitMQ or Kafka). You can then write a consumer to read the events.
