React JSON Visualizer

React JSON Visualizer is a lightweight JSON visualizer and JSON viewer dev tool that helps developers understand complex JavaScript objects and arrays through an interactive node-based UI.

It is designed to be DX-friendly, UI/UX focused, and simple to use.
You import one function, pass your data, and instantly see the JSON data flow.

What is React JSON Visualizer?

-Works with React, Next.js, Vanilla JS, and any browser environment

React JSON Visualizer turns any JavaScript object or array into a visual data graph.
-Each object becomes a node
-Nested objects and arrays are connected visually
-Primitive values stay inside nodes
-Users can drag, collapse, and explore data relationships
-This makes it ideal as a developer tool, debugging utility, or internal JSON inspector.
