kaptinlin / jsonrepair
High-performance Go library for repairing invalid JSON documents, tuned for LLM-generated output
Why this job: works in the areas we cover, but does not say which job it does
What it does
- Missing syntax repair. Adds missing quotes, commas, colons, and closing brackets when the intent is clear.
- Quote normalization. Converts single quotes and smart quotes into valid JSON string quotes.
- Comment removal. Removes JavaScript-style line and block comments.
- Wrapper cleanup. Strips Markdown code fences, JSONP callbacks, MongoDB wrappers, and ellipsis placeholders.
- Literal conversion. Converts Python-style None, True, and False into JSON literals.
