JSON Validator checks if a JSON string is properly formatted and meets structural requirements. JSON is widely used for data interchange between applications, APIs, and web services. A single missing bracket or comma can break an entire script or cause a page feature to fail. This tool quickly pinpoints any syntax errors, highlighting exactly where the structure is invalid. Once validated, you can confidently integrate the JSON into dynamic pages or third-party services. Whether you’re debugging an API response or editing config files, the JSON Validator ensures clean, parseable data every time.
