About This Tool
JSON Output Repairer recovers malformed AI JSON with deterministic cleanup steps so you can validate and use structured outputs safely in automation workflows.
Frequently Asked Questions
Does it use an LLM for repair?
No. Repairs are deterministic regex and normalization steps running locally in your browser.
Will this always recover broken JSON?
No. Deeply corrupted structures may still fail and require manual edits.
Is output uploaded anywhere?
No. All extraction, repair, and parsing happen client-side.
