Hi Siva,
Not sure if there's an easier way, but the below works and it's fast.
Step 1: File Management VBO - Read All Text from File
Step 2: Decision stage checking this: InStr([Text],NewLine() & NewLine())>0
Step 3a: If Decision is True/Yes, replace the double NewLine characters with a single NewLine character set using this: Replace([Text],NewLine() & NewLine(),NewLine())
Step 3b: Loop back to the Decision stage
Step 4: lf Decision is False/No, use File Management VBO - Write Text File to put the data back in the file without empty rows.
I tested this just now with 10k rows just in case.
