To parse a JSON file in Python, you can use the built-in json module. The json module provides two methods for serializing Python objects into a JSON formatted string: dumps() and dump(). The dumps() method returns a string, while the dump() method writes the JSON data directly to a file-like object.

To serialize a JSON file to a binary format, you can use the pickle module. The pickle module provides two methods for serializing Python objects into binary format: dumps() and dump(). The dumps() method returns a bytes object, while the dump() method writes the binary data directly to a file-like object.

Here is an example of how to parse a JSON file and serialize it to binary format in Python:

```python
import json
import pickle

# Load JSON data from file
with open('data.json', 'r') as f:
    data = json.load(f)

# Serialize data to binary format
binary_data = pickle.dumps(data)

# Write binary data to file
with open('data.bin', 'wb') as f:
    f.write(binary_data)
```

In this example, we first load the JSON data from the file 'data.json' using the json.load() method. We then serialize the data to binary format using the pickle.dumps() method. Finally, we write the binary data to a file named 'data.bin' using the 'wb' mode.
