JSONGenie - Beautify, Format & Visualize

About

JSONGenie: View raw JSON in an interactive, collapsible tree with syntax highlighting, instant type generation, and smart path copying.

JSONGenie is the smartest way to read and format JSON directly in your browser, automatically detecting JSON on any webpage—even if the page is cluttered—and transforming it into a clean, readable, and collapsible view. Ideal for developers, testers, and data analysts working with APIs and structured data.

🚀 Why JSONGenie?
JSONGenie transforms unreadable JSON strings into an organized, hierarchical display that makes even the most complex JSON structures easy to navigate. The collapsible interface is particularly helpful for large datasets, allowing you to focus on specific sections without getting lost in the details.

Whether you're debugging API responses, exploring data files, or just trying to make sense of JSON data, this formatter provides a professional, feature-rich alternative to viewing raw JSON.
