+
+This script takes a JSON file as input and generates a CSV file as output.
+
+## Prerequisites modules

+- Run `pip install json` to install the required external module.
+
+## How to Run the Script
+1. Make sure you have the necessary prerequisites installed.
+2. Download or clone the script `converter.py`.
+3. Open a terminal or command prompt.
+4. Navigate to the directory where `converter.py` is located.
+5. Run the script by executing the command `py converter.py`.
+
+## Additional Information
+- The script reads data from the input JSON file and converts it into CSV format.
+- It handles nested JSON structures and converts them into flattened CSV rows.
+- The output CSV file is created in the same directory as the input JSON file.
+- You can customize the behavior of the script by modifying the source code according to your requirements.
