Frequently Asked Questions

What is YAML?

YAML (YAML Ain't Markup Language) is a human-friendly data serialization format that's often used for configuration files. It's more readable than JSON and supports comments, making it popular for DevOps and configuration management.

What is flow style in YAML?

Flow style is a more compact YAML representation that's similar to JSON syntax. It uses braces and brackets instead of indentation, which can be useful when you want to minimize the number of lines in your YAML output.

Is my data secure?

Yes, all conversion is done entirely in your browser. No data is sent to any server, ensuring your information remains private and secure.

Why sort keys alphabetically?

Sorting keys can help maintain consistency in your YAML files, making them easier to read and compare. This is especially useful when working with version control systems or when you need to ensure a predictable output format.
