Overwrite csv file

I have to continue only one CSV file everyday. and columns also the same. and if rows want to change according to day process. how can i solve the problem?

Could you please elaborate?
Maybe with some screenshots for some clarity into the issue you are facing?

You can try using “Append To CSV” Activity and so the same file gets added with new rows .

does someone know how to overwrite a CSV file? I do not want to increase it, I want to overwrite
