Reading and navigating raw JSON responses in the browser is difficult, especially for large files. This extension automatically formats JSON with syntax highlighting, collapsible arrays/objects, item counts, and size indicators, making JSON data human-readable and navigable.

User navigates to a URL returning JSON (or JSONP). The content script detects JSON content, sends a message to the background service worker which injects CSS and executes a formatting script on the page. The raw JSON is replaced with a syntax-highlighted, collapsible tree view. User can customize appearance and behavior via the options page. Context menus allow formatting/encoding/decoding selected text on any page.

Target users: Web developers / API developers / Data analysts / Anyone working with JSON data in the browser

No network calls or external services to verify — extension is entirely client-side which makes analysis straightforward but there's minimal dynamic behavior to confirm
