+# json to csv convertor
+
+## Introduction
+
+This Python script allows you to convert json file to csv file and save them to a specified directory. It uses json and csv library to process json files and do manupulations accordingly.
+
+## Usage
+
+### Prerequisites
+
+Before using this script, ensure you have the following:
+
+- Python installed on your system.
+- Required libraries: `csv`, `json`, `python`
+
+### Running the Script
+
+1. Place the json file you want to convert to csv file in the same directory as this script.
+
+2. Replace the `input_file` variable with the name of your json file name with .json extention.
+
+```python
+input_file = 'json_data.json'
+python json_to_csv_with_nested_dict.py
+```
+
+### Information about  .py file
+
+1. `json_to_csv` function
+
+- This function defines the JSON to CSV converter. It takes three arguments:
+- Args :
+    - **json_data**: A JSON object or list of JSON objects.
+    - **csv_file**: The path to the CSV file to write the data to.
+    - **mapping**: A dictionary mapping JSON field names to CSV column headers.
+- Returns:
+    - None
+
+1. `flatten_json` function
+
+- This function flattens the JSON data. It works by recursively iterating over the JSON object and converting any nested JSON objects into a single level of key-value pairs.
+
+- Args :
+    - **obj**: A nested JSON object.
+
+- Returns:
+    - A flattened JSON object.
+
+### Output
+
+The script will create a directory named **csv_data.csv** in the same location as the script. Within this directory.
