## Quick...

## AI interpretation — verify before relying

Parses and repairs malformed JSON from LLMs, APIs, and user input by fixing missing quotes, commas, brackets, and other syntax errors, then returns valid JSON or Python objects.

Verdict: A well-maintained, dependency-free utility for handling real-world malformed JSON—particularly useful when integrating LLM outputs. MIT-licensed, actively developed, and ranked in the top 1000 PyPI packages with no known vulnerabilities. Straightforward to adopt as a drop-in replacement for json.loads().
