Transaction analysis web app

This article describes a web app built by a student to analyze personal bank transaction histories exported as CSV files. The tool allows users to load transaction data, categorize expenses by matching description patterns, and visualize spending with interactive charts using Chart.js. The author emphasizes data privacy (no server uploads) and shares the code on GitHub. It covers technical implementation details like CSV parsing, string splitting for categorization, and chart customization. The project is a practical example of using JavaScript for financial data analysis.
