JSON Formatter & Cleaner

About

JSON Formatter is a lightweight popup tool that helps you clean and format JSON instantly.

✅ What it does
• Sanitizes pasted JSON by removing hidden/invisible characters (like zero‑width spaces) and normalizing odd Unicode whitespace outside string values
• Validates JSON and shows a clear inline error when the input is invalid
• Minifies JSON structurally (safe minification using JSON serialization)
• Pretty‑formats JSON with readable indentation
• One textbox workflow: paste → click Format/Minify → copy

🔒 Privacy
This extension works entirely locally in your browser popup. It does not collect, store, or transmit your JSON.

💡 Tips
• Use “Format” to clean hidden whitespace issues and get a readable JSON output
• Use “Minify” when you need compact JSON for logs, payloads, or APIs
• Use Ctrl/Cmd + Enter to format quickly

Buttons included: Format, Minify, Copy, Clear.
