Would someone provide an example of extracting data from a char array?
When working with Arduino, cplusplus.com is your friend. Scroll down and look on the left side under (string.h). Lot's of great char functions there. Other useful functions such as iota() - cplusplus.com.
Here's one way to accomplish the parsing of the input data.
// Sketch uses 2064 bytes (6%) of program storage space.
// Global variables use 323 bytes (15%) of dynamic memory.
// Arduino IDE 1.8.9.
char line[] = &quot;04-23-2020,James&quot;;
char Name[100];
unsigned int Month, Day, Year;

// Make an attempt to validate the input data.
byte Counter = 0;

void setup(){

  Serial.begin(9600);

  char * pch = strtok(line, &quot;-,&quot;);

  while(pch != NULL){
    if(Counter == 0){Month = atoi(pch);}
    else if(Counter == 1){Day = atoi(pch);}
    else if(Counter == 2){Year = atoi(pch);}
    else if(Counter == 3){strcpy(Name, pch);}
    pch = strtok(NULL, &quot;-,&quot;);
    Counter += 1;
  }

  // Print out the data.
  if(Counter == 4){
    Serial.println(Month);
    Serial.println(Day);
    Serial.println(Year);
    Serial.println(Name);
  }
  else{
    Serial.println(&quot;Error&quot;);
  }

}

void loop(){}
