json_repair and jsonrepair
These are competitors offering the same core functionality (repairing malformed JSON from LLMs) in different languages, with the Python implementation vastly more mature and widely adopted based on its significantly higher stars and download metrics.
About json_repair
mangiucugna/json_repair
A python module to repair invalid JSON from LLMs
Provides syntax error correction for common LLM output mistakes—missing quotes, unescaped characters, incomplete arrays/objects—while preserving content integrity. Uses a two-stage approach: first attempts standard library `json.loads()` for performance, then falls back to a custom repair parser only on failure. Offers drop-in replacements for `json.load()` and `json.loads()`, with optional `skip_json_loads` and `strict` modes for performance tuning and validation control.
