Sobre esta herramienta
Paste messy or minified JSON and get it back cleanly indented and readable, or go the other way and minify it down for production. Invalid JSON shows exactly which line and column the problem is on, instead of just "unexpected token".
What does it do with invalid JSON?
It shows the parser’s error message along with the exact line and column it occurred at, so you can find and fix the problem quickly.
Is my data sent anywhere?
No, formatting and validation happen entirely in your browser.
