Building a Data Converter Website with AI: A Journey in Modern Web Development

Introduction

In this article, I’ll share my experience of building a dataconverter.net website using AI assistance. The project, Data Converter, is a web application that allows users to convert between various data formats like JSON, CSV, YAML, XML, HTML, Markdown, and more. What makes this project unique is that it was built with significant assistance from AI, demonstrating how AI can accelerate and enhance the web development process.

Project Overview

dataconverter.net is a Next.js-based web application that provides:

  • Real-time data format conversion between multiple formats
  • Support for 12+ input/output formats including JSON, CSV, YAML, XML, HTML, Markdown, URL Encoded, INI, TOML, Properties, and ENV
  • Modern, responsive UI using Material-UI
  • SEO-optimized structure with dynamic meta tags
  • Shareable conversion links with social media integration

Technical Stack

  • Frontend Framework: Next.js (latest version)
  • UI Library: Material-UI (MUI) with Emotion for styling
  • Key Dependencies:
    • yaml for YAML parsing
    • date-fns for date handling
    • @next/third-parties for third-party integrations
  • Development Tools:
    • ESLint for code quality
    • Jest for testing
    • Faker.js for test data generation

The AI Development Process

1. Project Setup and Architecture

The development process began with AI-assisted project setup. Using AI, we:

  • Generated the initial Next.js project structure
  • Set up the Material-UI theme configuration
  • Configured ESLint for code quality
  • Established a clean folder structure with separate components

2. Core Conversion Logic

The heart of the application is the conversion logic in utils.js, which includes:

  • Format detection using detectFormat function
  • Bidirectional conversion between formats:
    • JSON ↔ CSV
    • JSON ↔ XML
    • JSON ↔ YAML
    • JSON ↔ HTML
    • JSON ↔ Markdown
    • And many more combinations
  • Robust error handling for each conversion
  • Special character escaping and formatting

3. User Interface Components

The UI was built with reusable components:

  • Header.js: Navigation and format selection
  • QuickLinks.js: Popular conversion shortcuts
  • Footer.js: Site information and links
  • Custom Link.js component for enhanced navigation

4. SEO and Sharing

The application includes:

  • Dynamic meta tags for better SEO
  • Social media sharing integration
  • Copy-to-clipboard functionality
  • Shareable conversion links
