JSON to CSV

### JSON to CSV: A Comprehensive Guide

**Introduction:**
Converting JSON (JavaScript Object Notation) data to CSV (Comma-Separated Values) is a common task in data processing. JSON, widely used for data interchange, often needs to be transformed into CSV format for compatibility with various data analysis tools and software.

**Demonstration:**
Consider a JSON object:
```json
[
  {"name": "John", "age": 30, "city": "New York"},
  {"name": "Anna", "age": 22, "city": "London"},
  {"name": "Mike", "age": 32, "city": "Chicago"}
]
```
To convert this to CSV:
```csv
name,age,city
John,30,New York
Anna,22,London
Mike,32,Chicago
```

**Usage:**
1. **Online Tools:** Websites like json-csv.com allow easy conversion.
2. **Programming:** In Python, use libraries like `pandas`:
    ```python
    import pandas as pd
    import json
    
    data = json.loads('[{"name": "John", "age": 30, "city": "New York"}, {"name": "Anna", "age": 22, "city": "London"}, {"name": "Mike", "age": 32, "city": "Chicago"}]')
    df = pd.DataFrame(data)
    df.to_csv('output.csv', index=False)
    ```

**Conclusion:**
Converting JSON to CSV is essential for data manipulation and analysis. By leveraging online tools or programming libraries, this process can be streamlined, enhancing data usability across various platforms.
