Overview

The Excel Clone is a high-performance web application that allows users to create, manage, and calculate data within a dynamic spreadsheet interface. The app displays a responsive grid of cells where users can input raw data, apply text formatting like bold or italics, and navigate using standard keyboard shortcuts. The user can also write functional formulas in a dedicated formula bar, enabling the app to automatically perform calculations such as sums, averages, and basic arithmetic across different cell references. The app is built using modern web technologies such as Next.js, TypeScript, and Tailwind CSS. It features a custom-engineered reactivity engine to ensure that any change to a cell instantly updates all dependent formulas across the grid. The app was created for the purpose of demonstrating how complex, desktop-grade software logic—like dependency tracking and real-time data parsing—can be efficiently implemented within a modern browser environment.
