I have a sheet filled with data in each column and they all have different length in rows. Since I will need to audit the data everyday at 4pm, but other people will continue to add data in each column at the same time, so I am trying to find the last cell of every column and highlight that cell with value into red so I know its a cutoff.
But i am wondering how to find the last cell with value of every column and highlight it into red with Google Apps Script?
Thank you!
