| - | * **File Parsing:** Use Python's ''csv'' module to read the dataset. | + | |
| - | * **Data Formatting:** Convert hexadecimal strings (e.g., ''"0x1B8"'') using ''int(value, 16)'' if necessary to match the JSON keys. | + | |
| - | * **Load JSON:** Use the ''json'' library to load ''CAN_ID.json'', which contains ''can_id'', ''type'', and ''data'' fields. | + | |
| - | * **Logic:** For each row, extract the CAN ID, look it up in the JSON dictionary, and print the Timestamp, Action Name, and raw payload. | + | |
