How to print 5 values in rows and not columns to excel?

Hello.
I want to read 5 values of

I have several problems:

  1. I need my 5 values in a columns and not rows. New row will be in every inertia and I cant do that.

  2. How to write titles to the columns ? not working in the screenshot

screenshot provided of the output:

code:
const float referenceVolts = 5.0; // the default reference on a 5-volt board

int row_excel = 0; // number of lines

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
Serial.println("CLEARDATA"); // clear excel sheet
Serial.println("A,B,C,");

}

void loop() {
// put your main code here, to run repeatedly:
static const uint8_t analog_pins = {A0, A1, A2, A3, A4};
for (int i = 0; i < 5; i++)
{
int val = analogRead(analog_pins[i]);
float volts = (val / 1023.0) * referenceVolts; // calculate the ratio
Serial.println(volts); // print the value in volts

}
delay(1000);

}

I can't figure out the question(s) here, but if you want to present data in a certain way in Excel, then you can always create a sample Excel sheet of how you want it to look and then export that sheet as a CSV file. Then open you favourite text editor and see how the data has been laid out. Then simply have your sketch output the data in a similar format.

Thanks.
My output is rows of numbers and Im looking for columns and not rows .

1 2 3 4

and not
1
2
3
4

So don't use println

Separate the numbers with a comma instead of newline.

  for (int i = 0; i < 5; i++)
  {
    int val = analogRead(analog_pins[i]);
    float volts = (val / 1023.0) * referenceVolts; // calculate the ratio
    Serial.print(volts); // print the value in volts
    if (i < 4)
      Serial.print(',');
  }
  Serial.println();
