YAML FAQ

Are YAML and YML the same? What are YAML files used for?

Yes, .yaml and .yml are both file extensions for YAML files and are functionally identical. YAML files are widely used for configuration, data serialization, and settings in applications, CI/CD pipelines, Kubernetes, and more. The .yaml extension is preferred for clarity, but both are accepted.

Are YAML and JSON interchangeable? Which is better: YAML or JSON?

YAML and JSON are similar in structure and can often be converted between each other. YAML is more human-readable, supports comments, and is flexible for configuration files. JSON is stricter, widely used for APIs, and easier for machines to parse. The choice depends on your use case and requirements.

Are YAML files indent sensitive? Can YAML keys have spaces?

Yes, YAML relies on indentation (spaces, not tabs) to denote structure, and incorrect indentation will cause parsing errors. YAML keys can have spaces, but such keys should be quoted, for example: "my key": value.

Can YAML have comments? Can YAML import another YAML?

YAML supports comments using the # character, which can be placed on their own line or inline. YAML itself does not support importing other YAML files, but some tools and frameworks provide ways to include or merge files.

When and where did YAML come from?

YAML was first released in 2001. It was developed by Clark Evans, Ingy döt Net, and Oren Ben-Kiki as a human-friendly data serialization standard.

Does YAML support variables, anchors, and aliases?

YAML does not natively support variables like programming languages, but it does support anchors (&) and aliases (*) for referencing and reusing values within the same file. Some parsers and tools extend YAML to allow more advanced variable-like features.

How do you escape characters, colons, or quotes in YAML?

YAML uses backslash (\) as an escape character for special characters in double-quoted strings. To use a colon in a value, wrap the value in quotes, e.g., key: "value:with:colons". To include quotes inside a double-quoted string, escape them with a backslash, e.g., key: "He said: \"Hello\"".
