JSON Viewer

A modern web application that helps developers visualize, format, and validate JSON data with ease.

Features

• Real-time JSON formatting and validation
• Syntax highlighting with Ace Editor
• Auto-formatting on paste
• Error detection and reporting
• Clean and modern UI

Why I Built This

While working with APIs and JSON data daily, I found myself frequently switching between different JSON formatting tools. None of them had exactly the combination of features and user experience I wanted. This project was born out of the need for a fast, reliable, and user-friendly JSON formatting tool.

Technical Implementation

• Frontend Framework: React with TypeScript
• Code Editor: Ace Editor for syntax highlighting and editing capabilities
• Formatting: Prettier for consistent JSON formatting
• Styling: Custom CSS with CSS variables for theming
• Error Handling: Real-time JSON validation with detailed error messages
