How to filter the unnecessary attributes from JSON TO DATA output

Hi @Somnath_Das

Whats wrong with Select Attributes?

Instead of manually selecting the attribute is there a way to automate the selection based on a criteria like null etc

You can use 'regular expression' in Select Attributes to define a rule what to be selected

@ceaperez can u please elaborate your comment.

Hi @Somnath_Das, 
I don't know what's wrong with Select Attributes Operator, in this case is the right choice. The Work on Subset Operator,  let  you to choose a subset of Attributes, similar to Select Attributes Operator.
