What is JSON Formatter?
A JSON formatter takes raw or minified JSON data and reformats it with proper indentation and syntax highlighting for easy reading. It also validates your JSON, catching syntax errors like missing commas, mismatched brackets, or invalid values.
How to Use
- Paste your raw or minified JSON into the input area
- The tool automatically formats and validates the JSON
- Adjust indentation level (2 or 4 spaces) to match your preference
- Copy the formatted output or download it as a file
Frequently Asked Questions
- What causes 'invalid JSON' errors?
- Common causes include trailing commas after the last item, single quotes instead of double quotes, unquoted keys, and missing closing brackets or braces.
- What is the difference between JSON and a JavaScript object?
- JSON requires double-quoted keys and string values, doesn't allow trailing commas, and cannot contain functions or undefined. JavaScript objects are more flexible.
- How do I minify JSON?
- Minifying removes all whitespace, newlines, and indentation to reduce file size. Use the minify option to compress your JSON for production use.
