Do you want to see "AABBCCDD" as AA BB CC DD (the separate hex bytes)? The following sketch saves them in the array named: byteArray[].

void setup()
{
  Serial.begin(9600);
  char data[] = "AABBCCDD";

  unsigned long x = strtoul(data, NULL, 16);
  //Serial.println(x, HEX);//AABBCCDD
  int i = 0;
  byte byteArray[4];

  do
  {
    byteArray[i] = x % 0x100;
    x = x / 0x100;
    i++;
  }
  while (x != 0);

  for (int k = 3; k >= 0; k--)
  {
    Serial.println(byteArray[k], HEX);
  }
}

void loop() 
{

}
