Working with JSON is a daily task for developers, and messy or invalid JSON can waste hours of debugging time. A good JSON formatter saves you from those headaches.
What Does a JSON Formatter Do?
- Beautify — Takes minified JSON and formats it with proper indentation
- Validate — Checks for syntax errors and shows exactly where they are
- Minify — Removes whitespace for smaller file sizes
- Tree View — Navigate complex JSON structures visually
Common JSON Errors and How to Fix Them
Trailing Commas
{ "name": "John", "age": 30, } ← trailing comma!JSON doesn't allow trailing commas. Remove the last comma before the closing brace.
Single Quotes
{ 'name': 'John' } ← wrong!JSON requires double quotes. Use "name": "John" instead.
Unquoted Keys
{ name: "John" } ← wrong!All keys in JSON must be quoted: "name": "John"
