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.

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.

This is a pretty useful extension. I use JSONGenie daily while building UI that consumes APIs. The auto-detect and formatting save my time, and I really appreciate the dark/light theme toggle for eye comfort. I can dive into nested structures, understand the data flow, and copy values instantly.
