json_format
Validate and pretty-print JSON strings with configurable indent width (2 or 4 spaces). Detects parse errors in raw or minified JSON and returns formatted output or error details.
Instructions
Validate and pretty-print a JSON string at a configurable indent width (2 or 4 spaces). Use to detect parse errors in raw JSON or to normalize minified JSON for readability; for schema validation or data transformation, apply your own logic. Runs JSON.parse + JSON.stringify locally with no network calls. On success, returns the formatted JSON string. On parse failure, returns an error message describing the position and nature of the syntax error.
