About JSON Formatter & Tools

A fast, secure, and beautiful way to format, validate, and compare your JSON data — right in your browser.

What is JSON Formatter?

JSON Formatter is an online tool designed to make working with JSON data simple and pleasant. It helps developers, analysts, and anyone who deals with APIs or configuration files to format, beautify, validate, and compare JSON instantly — without worrying about syntax errors or missing commas.

Our Mission

Our goal is to create developer-friendly, privacy-first tools that just work. No data is ever uploaded to any server — everything happens right in your browser using secure client-side code. Whether you need to clean up messy JSON, validate an API response, or compare two files, our tools are built to save you time.

Tools Included

JSON Formatter – Beautify and structure raw JSON data for readability.
JSON Viewer – Explore complex JSON objects in a collapsible tree view.
JSON Beautifier – Add indentation and clean up minified or messy JSON.
JSON Compare – Find differences between two JSON objects quickly.
JSON Validator – Instantly detect syntax errors and validate structure.

Privacy & Security

Your JSON never leaves your device. Everything runs locally in your browser using JavaScript. That means your private data, API responses, or configuration files are completely safe.

Built for Developers
