これができて嬉しい。さあ、始めよう：

```python
import pandas as pd
import json

# Load the externos.csv file into a Pandas DataFrame
df_vra = pd.read_csv('externos.csv', separator=';')

# Create an empty dictionary to store the extracted information
data = {}

# Iterate through each row in the DataFrame
for index, row in df_vra.iterrows():
    # Retrieve the values for the RUT, DV, and Names columns
    rut = row["RUT"]
    dv = row["DV"]
    names = row["Names"]
    
    # Store the values in the dictionary
    data[index] = {"RUT": rut, "DV": dv, "Names": names}

# Write the dictionary to a json file
with open('extracted_data.json', 'w') as f:
    json.dump(data, f)

# Display the contents of the json file
with open('extracted_data.json', 'r') as f:
    print(json.load(f))
```

PandasやPythonに関する質問がありますか？
I'm glad to do this. Here we go:

```python
import pandas as pd
import json

# Load the externos.csv file into a Pandas DataFrame
df_vra = pd.read_csv('externos.csv', separator=';')

# Create an empty dictionary to store the extracted information
data = {}

# Iterate through each row in the DataFrame
for index, row in df_vra.iterrows():
    # Retrieve the values for the RUT, DV, and Names columns
    rut = row["RUT"]
    dv = row["DV"]
    names = row["Names"]
    
    # Store the values in the dictionary
    data[index] = {"RUT": rut, "DV": dv, "Names": names}

# Write the dictionary to a json file
with open('extracted_data.json', 'w') as f:
    json.dump(data, f)

# Display the contents of the json file
with open('extracted_data.json', 'r') as f:
    print(json.load(f))
```

Is there something I should explain you contained or do you have other Pandas or Python questions?
