Instantly format messy JSON code into readable text, validate for errors, or minify it to save space.
What we do
Servers often spit out JSON data as one giant, unreadable block of text. Paste it here and click Beautify JSON to instantly structure it with perfect line breaks and indentations for easy reading.
Missing a single comma or a quotation mark will completely break your application. Our live validator instantly detects syntax errors, and our Auto-Fix tool can automatically correct common mistakes.
Need to send a massive JSON payload over the network? Use the Minify JSON button to instantly strip out all spaces and line breaks, compressing your data to the absolute smallest file size.
Every developer has their own coding style. Use our settings panel to choose exactly how your JSON is indented: 2 spaces, 3 spaces, 4 spaces, or classic tab characters.
Yes, this developer utility is 100% Free. You can format massive JSON objects and arrays as many times as you want without any restrictions or sign-ups.
Your API keys, user data, and secure server strings are completely safe. This formatter runs entirely Client-Side inside your browser and never uploads your JSON to any server.
