jsonrepair is a JavaScript utility designed to automatically repair malformed or invalid JSON documents by correcting common syntax and formatting issues. The library is capable of fixing problems such as missing commas, trailing commas, invalid quotes, unescaped characters, incomplete values, comments, and improperly formatted structures while preserving the intended data as accurately as possible. It is especially useful in workflows involving AI-generated content, manually edited configuration files, or unreliable external APIs where malformed JSON frequently occurs. jsonrepair supports both browser and Node.js environments, making it suitable for client-side validation tools and backend processing pipelines alike. The project focuses on automation and fault tolerance, reducing the need for manual cleanup of corrupted JSON data. Its lightweight architecture and practical functionality have made it valuable for modern applications that process unpredictable structured text.
