JSON validator
Validate JSON syntax locally in your browser and inspect line-and-column parse errors.
Runs locally in your browser. json park never receives this JSON text.
Common uses
- Check whether pasted JSON is valid before using it in an API, test, or config file.
- Find syntax failures with line and column detail instead of scanning by eye.
- Validate sensitive payloads locally without sending them to a server.
Details
Does the validator upload my JSON?
No. Syntax validation happens in your browser through the local JSON worker.
Is this the same as JSON Schema validation?
No. This tool checks whether JSON text parses. Use the JSON schema validator when you need to validate values against a schema.
