Frequently Asked Questions
YAML uses indentation and is more human-readable, supports comments, and allows multiline strings. JSON uses braces/brackets, is more compact, and is native to JavaScript. YAML is popular for config files, JSON for APIs and data exchange.
YAML maps directly to JSON: YAML mappings become JSON objects, sequences become arrays. Paste YAML, parse it, then stringify as JSON. Watch for YAML-specific features (anchors, multiline strings) that need special handling.
Use 2 spaces for indentation (not tabs). Key-value pairs: key: value. Lists use - prefix. Multiline strings: | for literal, > for folded. Comments start with #. Strings usually do not need quotes unless containing special characters.
Common errors: using tabs instead of spaces, inconsistent indentation, missing space after colon, unquoted special characters (: @ #), or invalid escape sequences. YAML is whitespace-sensitive; indentation must be consistent.
