FAQ

How does the tool handle complex indentation and nested structures when converting to YAML?

The tool has a smart indentation engine built in. You can customize the number of spaces (typically 2 or 4) to match your project conventions. It automatically converts JSON curly braces {} to YAML colons : and arrays to hyphens -, ensuring the generated YAML is well-structured and standards-compliant.

Does the converted YAML support anchors and references?

While the automatic conversion focuses on basic structures, the generated YAML is fully compatible with advanced YAML features. You can manually add anchors (&) and references (*) directly in the output to reuse config blocks, which is very useful for writing complex Kubernetes or Docker Compose files.

Can it still convert if the JSON data has formatting errors?

Yes. The tool has powerful JSON auto-repair built in. If your input contains syntax errors (like unclosed quotes or brackets), it will attempt smart repairs and highlight them, ensuring you can still generate usable YAML configs even when the source data isn't perfect.
