Hi @Anjali_Rani ,
Sharing my suggestion on the question.
In the end of your work flow. use excel application scope inside use the below activity to insert blank row in the second position.
Insert / Delete rows acitivity → insert values in the parameters No Rows = 1,
Position = 2 , Change mode → Add
once you create empty row → Use bulid data table activity and insert the columns and your values you want insert in the second row the output of the build data table activity is datatable with the values you mentioned in the screenshot.
Use write range activity and assign the Data table whiich you got from build data table and enter Range “B1” and uncheck the add data headers.
the above flow will help what you want. thanks
