arduino - Saving data on excel -

is possible save on different excel sheets after number of data collected? data logging using arduino in real time , aiming create new sheet every day. or @ least possible change name of .csv?

why not create function formats data csv on arduino side , prints out on serial monitor. can copy output on serial monitor , paste .csv file. write small program takes output on serial monitor , saves .csv file. here example of code on arduino side

void print_data(int x, int y) {     serial.print(x, dec);      serial.print(",");     serial.print(y, dec);         serial.println(); }
