JSON Repair (LLM Output Fixer)
How it works
- 1.
Paste broken JSON
Type a code (for example 404) or a keyword (for example 'auth' or 'redirect'). The list filters live and shows only matching codes.
- 2.
Let it repair
Categories 1xx through 5xx are color-coded. Blue = informational, green = success, yellow = redirect, orange = client error, red = server error.
- 3.
Copy or edit further
Every code comes with a bilingual explanation (DE/EN) plus typical causes and recommended actions. Perfect for debugging or API docs.
