JSON (JavaScript Object Notation) is everywhere—from APIs and configuration files to data storage and web apps. But let’s be honest: raw JSON can be ugly. Without formatting, it’s a wall of text that’s hard to read and even harder to debug. That’s where PrettyJson.site comes in—a free, browser-based tool that makes your JSON instantly more readable, valid, and developer-friendly.
1. Paste or Upload Your JSON
Getting started is effortless. Simply copy your JSON and paste it into the editor at PrettyJson.site, or drag-and-drop a .json file. No installation, no sign-up, and most importantly—no data leaves your browser.
“PrettyJson.site processes everything locally, so even sensitive API keys or private data remain secure.”
2. Beautify, Minify, and Validate with One Click
Once your JSON is loaded, you have three powerful options at your fingertips:
- Beautify – Format JSON with indentation and line breaks for maximum readability. Shortcut: Ctrl/⌘ + Enter.
- Minify – Strip away whitespace and line breaks for a compact version. Shortcut: Ctrl/⌘ + Shift + M.

3. Copy, Download, or Share
When you’re done, export your work effortlessly:
