Validate JSON for syntax errors with precise line and column reporting. Catch trailing commas, unquoted keys, and structural issues before they reach production.
Why Validating JSON Data Is Essential
JSON is the universal data interchange format for APIs, configuration files, and data pipelines. A single syntax error -- a missing comma, an unquoted key, or a trailing comma after the last element -- can cause an entire API response to fail parsing, a build pipeline to break, or a configuration to be silently ignored. Catching these errors before they reach production saves debugging time and prevents downstream failures.
