Frequently Asked Questions
Answers to users' most common concerns
What is YAML format?
YAML (YAML Ain't Markup Language) is a human-readable data serialization standard commonly used for configuration files and data exchange. It uses indentation to represent hierarchy, is more readable than JSON, and is widely used in tools like Kubernetes and Docker Compose.
Why format YAML?
Formatting YAML improves configuration file readability and consistency. Proper indentation and formatting helps avoid syntax errors and facilitates team collaboration and configuration management.
Why is YAML indentation important?
YAML uses indentation to represent data hierarchy. Incorrect indentation can cause parsing failures or data structure errors. It's recommended to always use spaces instead of tabs and maintain consistent indentation levels.
How does the tool handle comments?
Our tool supports complete comment preservation functionality, maintaining original comment content and positions during formatting to ensure configuration file documentation integrity.
What file sizes are supported?
The tool can handle most common YAML file sizes. For particularly large configuration files (over 5MB), we recommend processing in chunks for better performance.
What's the difference between YAML and JSON?
YAML is more readable, supports comments and multi-line strings, uses indentation for structure; JSON is more compact, parses faster, but doesn't support comments. They can be converted between each other for different use cases.
