About JSON Tree Viewer
Paste any JSON string and watch it collapse into a clean, expandable tree. Nested objects unfold one level at a time, so you can navigate a deeply nested API response or config file without scrolling through a wall of raw text. Click a node to expand or collapse it — that's the whole interaction, and it's exactly what you need when you're trying to find one buried key.
This sits comfortably in the developer tools category alongside utilities built for quick inspection rather than heavy editing. If you also need to spot what changed between two JSON blobs, Text Diff is worth a look for that side-by-side comparison.
Works best on a larger screen because a wide tree with several levels of nesting takes real horizontal space — on a phone, deeper branches can feel cramped. No account needed; just paste and explore.
