Online JSON Formatter & Validator

Why use a JSON Formatter?

JSON (JavaScript Object Notation) is the language of the web APIs. However, API responses often come as a single, minified line of text to save bandwidth. This makes it impossible for humans to read or debug. Our JSON Formatter solves this by adding proper indentation and spacing.

Core Features

• Beautify: Converts messy, minified JSON into a clean, hierarchical structure with 2-space or 4-space indentation.
• Minify: Removes all unnecessary whitespace and newlines to reduce file size for production usage.
• Validate: Checks your JSON syntax for errors (like missing commas or unclosed brackets) and tells you exactly where the problem is.

Who needs this?

This tool is essential for Web Developers working with REST APIs, Data Analysts parsing JSON datasets, and Students learning data structures.
