Frequently Asked Questions
How does JSON repair work?
Our repair system uses a multi-layered approach: first the JSONRepair library for fast, reliable fixes, then basic pattern matching, and finally AI providers (DeepSeek, OpenRouter, Groq) for complex issues.
What repair methods are used?
1) JSONRepair library - Fast, accurate repair for most common issues. 2) Basic repair - Pattern-based fixes for simple syntax errors. 3) AI repair - DeepSeek and other AI providers for complex structural problems.
Is there a size limit for AI repair?
Yes. For reliability, AI repair supports inputs up to approximately (~18000 characters) per request. Larger JSON files can usually be fixed using the local JSONRepair/basic methods, or you can split them into smaller chunks before applying AI repair. Alternatively, you can use the validate utility to manually repair the JSON.
Do I need API keys?
No. You don't need any API keys. For complex cases, we enhance results using our DeepSeek API integration (managed by us) on top of local JSONRepair and built-in fixes—so it works out of the box. When AI is used, your JSON is sent to DeepSeek to complete the repair. On the free plan, you can use up to 10 AI repairs (DeepSeek) per day.
How accurate is the repair process?
Very high accuracy for common issues using the JSONRepair library. Basic pattern matching handles simple syntax errors. AI providers provide intelligent analysis for complex structural problems when needed.
