Description

Pretty JSON Viewer automatically detects standalone JSON responses in your browser and replaces the raw text with a clean, collapsible tree. It’s designed for engineers debugging APIs who want to quickly understand complex payloads without copying JSON into external tools. Key features * Automatic detection: When you open a page that is just JSON, the extension swaps in a dedicated viewer instead of leaving you with a wall of text. * Tree viewer: Explore nested objects and arrays with an intuitive, collapsible tree that’s easy to scan and navigate. * Search: Find keys and values across the entire payload with keyboard-friendly search controls. Safe mode for large JSON: Automatically detects very large payloads and limits deep expansion to * keep the UI responsive. You can opt in to loading large subtrees when you need them. Breadcrumbs & pinned paths: Quickly see where you are in the structure, and reuse important paths for faster navigation. * Themes & font size: Switch between multiple themes and adjust font size from the toolbar so the viewer fits your environment.
