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.

Great tool for developers working with APIs. JSONGenie automatically formats messy JSON into a clean tree view, which makes debugging responses much easier. The syntax highlighting and quick path copy features are really handy.
Awesome 🤩
useful tool
For some reason this extension messes with the layout of old Reddit, and I'm not really sure why. 1. When clicking the + to collapse reddit comments, it completely hides the comments, instead of just collapsing them. 2. It also hides the inline media viewer button, as implemented in the Reddit Enhancement Suite extension. Very weird/annoying bugs and I'm not sure why this extension is causing this to happen, but I had to force JSONGenie to only function on sites I set manually, in the extension settings. The extension works fine otherwise, but this problem is kind of annoying. I'm not sure where else on the web it causes weird issues like this, but worth keeping in mind, if you notice stuff missing or functioning different across various sites.
Useful Extension. Thanks...
very useful for JSON data use.
A fast, responsive tool packed with features, easy to use, and still with many more to explore.
very useful and practical for JSON data use , features like collapsing all key nodes , copying full key and value using double click is very useful, recommended for developer community.
Simple and easy tool to view and manage json data especially with dark theme
very useful...
