🌦️ Weather Flask

A simple Flask-based web application that fetches real-time weather data from the OpenWeatherMap API and provides it in multiple formats — JSON, CSV, Excel, and XML. Easily configurable and extendable, ideal for learning REST APIs, file conversion, and basic Flask routing.

🚀 Features

• Fetch real-time weather data for any city

• Convert and export weather data in:

  • JSON (default)
  • CSV
  • Excel (XLSX)
  • XML

• Modular structure with separate modules for fetching, processing, and converting data

• Clean and simple Flask API endpoints
