What types of broken JSON can it fix?

Our fixer handles: trailing commas, single-quoted strings, unquoted keys, Python booleans (True/False/None), JavaScript/C-style comments (// and /* */), markdown code block wrappers (```json), missing outer braces, and JSON embedded in prose text.

Does it use AI to fix JSON?

No AI API calls are made. Despite the name, our fixer uses sophisticated pattern matching and parsing algorithms that run entirely in your browser. It's called 'AI JSON Fixer' because it's designed to fix the malformed JSON that AI models commonly output.

Will it change my data values?

No. The fixer only corrects structural issues. Your data values, keys, and overall structure remain intact. Only syntax issues are repaired.

What if the JSON is too broken to fix?

If the JSON cannot be automatically repaired, you'll get a clear error message explaining what went wrong. The tool fixes the vast majority of common AI output issues.
