Overview

Click to format the current page’s JSON with a fast, collapsible viewer—no auto-run.

Click the extension to format the current page’s JSON into a fast, collapsible tree. Handles very large JSON (tested up to ~100 MB) with instant expand/collapse, supports multiple themes, and includes lightning-fast search through nested objects. Runs only when you click; no data leaves your browser. Feature list * Click-to-run: only activates when you press the extension icon (no background auto-run). * Large JSON ready: works smoothly on big payloads (tested up to ~100 MB). * Fast on big JSON: instant expand/collapse powered by react-obj-view. * Lightning-fast search: find keys/values deep inside nested objects. * Multiple themes: switch looks; preferences stay local. * Reader-friendly layout: collapsible tree with line numbers option.
