About this tool
Turn a wall of JSON into something you can navigate. Every object and array collapses, arrays show their length, and clicking a node copies its path so you can reference it in code.
When you would use it
- Finding one field in a deeply nested API response
- Understanding the shape of an unfamiliar payload
- Copying the exact path to a value for use in code
Worked example
{"user":{"name":"Ada","roles":["admin","editor"]}}
▾ user {2}
name: "Ada"
▾ roles [2]
0: "admin"
1: "editor"
Things worth knowing
- Trees larger than a thousand nodes render incrementally, so very large documents stay responsive.
- URLs in values are rendered as links, and image URLs preview on hover.
Questions
Frequently asked
Can I search inside the tree?
Yes — the search box matches both keys and values, expands whatever it finds and highlights each match.
Is my data uploaded anywhere?
No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
Does it work offline?
Yes. JSONWorks is installable as a progressive web app and caches itself on first visit, so every tool keeps working without a connection.
