This project is a full-stack web application that allows users to upload Excel files and instantly generate dynamic bar or pie charts from the data. It features a React frontend with Tailwind CSS for styling and an Express.js backend for handling file uploads and data extraction using ExcelJS. Users can choose columns for labels and values, preview the data in a table, and switch between chart types for flexible data visualization.

In this project, I built a web scraper using Python, BeautifulSoup, and Requests to extract data from websites. The scraper automates data collection for analysis and visualization, making it useful for market research and trend analysis.

Retail Data Analysis

Tools Used: Excel, Power BI

For this project, I utilized Excel and Power BI to analyze a retail dataset. I used pivot tables to calculate key statistics like sales performance, customer trends, and product insights. I created a visual dashboard using Power BI to represent the data and identify key insights that could help improve sales and customer engagement.

Tools Used: Tableau

This project leverages Tableau to analyze and visualize industry changes over time.
