JsonLoom: Visual JSON Mindmap

Overview

Visualize raw JSON text from any page as an interactive, collapsible node graph mindmap.

JsonLoom is a premium utility built for developers, integration engineers, and API designers to navigate and inspect complex JSON payloads visually. Rather than looking at nested braces and thousands of lines of code inside text views, convert JSON structures into clean interactive mindmap graphs. Expand and collapse node elements, query values, inspect data formats, and copy paths with ease. Features: - 📊 **Visual Mindmap Layout**: Render nested JSON objects and arrays as floating nodes powered by dynamic physics layouts. - 🎨 **Type Presets**: Instantly distinguish data types (Strings, Numbers, Objects, Arrays, Booleans, Nulls) by custom color-codings. - 🔍 **Filter Node Queries**: Type search keys or details inside the filter bar to highlight matching nodes in the map. - 📋 **1-Click Clipboard Paths**: Inspect nodes to view computed JSON paths (e.g. `root.details.stats[0]`) and copy them to your clipboard in one tap. - 🔄 **Spring Layout Reset**: Reset pan/zoom dimensions or recompute node forces easily. Manage nested schema formats cleanly and speed up your API integrations. Privacy Note: JsonLoom values your privacy. Your copy-pasted and loaded JSON data is processed entirely locally on your device's browser memory—our extension never transmits or exposes your files to external hosts. The extension is 100% free.
