plx-daq columns problem

Hello
I make a project with arduino mega.
I want to measure more than 6 voltages at once and export the data to excell.I try to finish my code but my problem is that i cant send data to different columns.The only data that i read to excell is the time and the voltage from A0 Pin

void setup() 
{
  Serial.begin(9600); 
  Serial.println("CLEARDATA");

  Serial.println("LABEL,Time,Block 1,Block 2,Block 3,Block 4"); 
  Serial.println("RESETTIMER"); 
}

void loop() 
{
  int sensorValue = analogRead(A0);
  float voltage = sensorValue * (5.0 / 1023.0);
  Serial.println(voltage);
  delay(1000);

  sensorValue = analogRead(A2);
  voltage = sensorValue * (5.0 / 1023.0);
  Serial.println(voltage * 3);
  delay(1000);

  Serial.print("DATA,TIME,"); 
}

moderator: added code tags and reformatted code (use CTRL-T in the IDE) to make it more readable

thanks..

any suggestion about my problem??

You need to put a comma between each voltage, like this:

void loop()
{
  int sensorValue = analogRead(A0);
  float voltage = sensorValue * (5.0 / 1023.0);
  Serial.print(voltage);
  Serial.print(",");

  sensorValue = analogRead(A2);
  voltage = sensorValue * (5.0 / 1023.0);
  Serial.println(voltage * 3);
  delay(1000);

  Serial.print("DATA,TIME,");
}
