Thank you @Shubham_Dutta and @raja.arslankhan for your response -but I believe I will have to rephrase my question, here my requirement is to write a value below the month, month already exists in sheet .
eg: When BOT runs on Sep it will go fetch a value from a site and update the Sept Column with the value and next month when BOT runs it has to update value under the OCT column.
sorry for the confusion earlier.
