JSON (JavaScript Object Notation) is a lightweight data-interchange format. When it's minified or malformed, it's hard to read and debug.

Benefits of formatting

• Improves readability.
• Makes it easier to spot syntax errors.
• Helps when comparing structures or preparing sample data.

How to use the JSON Formatter

Paste JSON into the tool and click Format & Validate. The tool will pretty-print valid JSON or show the parsing error.
