I am using apache nifi to convert json to csv. I want to change the headers of the generated csv . Is there any specific processor for this. I know how to achieve this using ExecuteScript processor but is there any easy approach. Ex. "_id", "name","time" to "id", "browser_name","duration"
Instead of using the function: prepend (this just shifts your data), how do you do an outright replace for the header row? I tried using Literal search, but I end up having strange characters when the replace occurs
