Stop JSON Errors: Validate Your Data Instantly

JSON is the language of the web, but it's unforgiving. A single trailing comma (valid in JS but invalid in JSON) can cause an API to fail or a config file to be rejected.

Common JSON Pitfalls

• Trailing Commas: {"a": 1,} is invalid.
• Single Quotes: JSON requires double quotes "key": "value".
• Unescaped Characters: Newlines and tabs inside strings must be escaped.

The Solution

Don't rely on your eyes. Paste your code into our JSON Validator. It will parse the input and point out exactly where the error is, often with a helpful message explaining what's wrong.
