UART communication with Putty

I am printing 8 ADC values out to Putty and save the log file as "*.csv".

But when I checked the printed values, there are no taps between them even though I added '\t'.

for example, if the values were "1, 2 3, 4, 5, 6, 7, 8", the saved value in CSV file is "12345678".

I am using FreeRTOS  and the code is attached below.

I also tried to print all the values together with one variable. 


void uart_task(void)
      char TEMP[32];

      TickType_t xLastWakeTime;

      uart_config.srcclk = DEMO_UART_CLK_FREQ;
      uart_config.base = DEMO_UART;

      UART_RTOS_Init(&handle, &t_handle, &uart_config);



            xLastWakeTime = xTaskGetTickCount();

            for (int i = 0; i < NOS; i++ )

                  sprintf(TEMP, "%d",OFFSET[i]-ADC_VALs[i]);
                  UART_RTOS_Send(&handle, (uint8_t *)TEMP, strlen(TEMP))


      UART_RTOS_Send(&handle, "\r\n", strlen("\r\n"));
      vTaskDelayUntil(&xLastWakeTime, 20);
