@Anandhakumar Cholendran - Thanks for the question and using MS Q&A platform.Here are the steps to add headers to txt file using ADF Dataflow:
Step1: Create a data flow and add a source and point to the text file located in the storage account and make sure to the ignore selecting First row as header option.
Step2: Repeat the same for adding the sink where you want the output to be stored.
Step3: Select Sink and go to mapping option and I would suggest you disable Auto mapping in Sink's Mapping tab and then name Output columns as column header name as per your requirement.
Step4: Click on datapreview option to shows the data with headers to output file.
Step5: Add a Data flow activity and attach the dataflow created and run.
