Hi.
You can take a look at our guide on how to use the microSD card. It shows how to read data from files: https://randomnerdtutorials.com/esp32-microsd-card-arduino/#readFile
If you know how the data is arranged in the file, you can through string manipulation, get the data that you want and save it in a variable. Then, compare with another variable (the data on the serial monitor).
