JSON Repair & Formatter

Repair classic model JSON injuries: trailing commas, comments, cut tails.

Can you salvage the missing-brace response?

Engine 1.0.0 · studio

Paste or edit the damaged response, then repair it. Fixes are listed explicitly so you learn the injury patterns.

Method

  • Repairs the classic injuries in order: strips // and /* */ comments, converts single quotes, removes trailing commas, closes unbalanced strings and brackets.
  • Every fix is listed explicitly — the point is learning to recognize the injury patterns, then preventing them with response_format / schema enforcement.
