Validate JSON syntax, find errors with line numbers, query with JSONPath, and view statistics.
About JSON Validator
JSON Validator is a free online tool that checks your JSON for syntax errors and provides detailed feedback including the exact line number where errors occur. It also features JSONPath querying to extract specific values and comprehensive statistics about your JSON structure including key count, nesting depth, and data size.
How to Use
Paste your JSON into the input area. The tool automatically validates it and shows whether it's valid or invalid. If invalid, you'll see the error message with the line number. For valid JSON, you can use the JSONPath field to query specific values (e.g., 'users[0].name') and view statistics about your JSON structure.
Common Use Cases
- Debugging JSON API responses with syntax errors
- Validating configuration files before deployment
- Querying specific values from large JSON documents
- Analyzing JSON structure complexity and size
- Quick JSON syntax checking during development
