Hi @balupad14 @ClaytonM @aksh1yadav @KarthikByggari
I download the excel sheet using email activities and renamed the sheet name, when i want to add column names (already having data in it with column names) It was adding. with this it adding other columns too. After this i have to login into website and it will generate the names randomly i given loop to repeat and it should be written to excel that already having the data in it (From the mail which i have downloaded it ) . It is not writing the data to it when i added write range and append range. using append range it just writing only into empty excel sheet but not into already having data in it.
