Secure JSON Repair

Format & repair JSON — 100% offline, no server

What it does

I built this because I was tired of pasting API secrets into random online JSON formatters. Everything runs 100% locally in your browser. Zero server calls. Turn off your WiFi and it still works perfectly. Key features: - Auto-Repair — fixes trailing commas, unquoted keys, single quotes automatically - Collapsible Tree View with Copy Node Path - Sort Keys A→Z recursively - Syntax highlighting — One Dark Pro theme - Light & Dark mode - 100% free, no ads, no tracking
