+# JSON to XML Converter
+
+A standalone Python script that converts a JSON file into an XML file. This script is useful for transforming JSON data into a structured XML format for use in systems that require XML-based input.
+
+## Features
+
+- Reads JSON data from a file.
+- Converts nested JSON objects and arrays into XML elements.
+- Outputs well-structured XML files with proper formatting and indentation.
+- Adds a standard XML declaration header (`<?xml version="1.0" encoding="UTF-8"?>`).
+
+## Setup Instructions
+
+### Prerequisites
+- Python 3.6 or later installed on your system.
+
+### Installation
+1. Clone or download this script to your local system.
+2. Save the JSON data you want to convert in a file named `input.json` in the same directory as the script.
+
+### Running the Script
+1. Open a terminal or command prompt.
+2. Navigate to the directory containing the script.
+3. Run the script using the following command:
+   ```bash
+   python json_to_xml.py
+The script will generate an XML file named output.xml in the same directory.
+
+## Output
+
+Display images/gifs/videos of output/result of your script so that users can visualize it
