How to filter the unnecessary attributes from JSON TO DATA output

Somnath_Das

From the output of the JSON TO DATA operator I want to select only specific attributes out of all. Without using SELECT ATTRIBUTE is there any other way? Please suggest me a way.

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

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.

Whats wrong with Select Attributes?

Somnath_Das

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