Hello, why parabola sometimes expanding json values to null ?
Does your JSON data maintain a consistent schema? It may be possible that your JSON can only be parsed until a certain level.
If your JSON data is consistent, but there are some cells that are blank before your JSON is expanded, you may want to use a “Sort rows” step to push all blank cells to the bottom of your column. That can sometimes help parse your JSON.
Feel free to send an example of your data, and we can look into it further.
