FAQ
What's the difference between YAML and JSON?
YAML is a superset of JSON, more readable: supports comments (#), multi-line strings, anchor references. JSON is better for program-to-program data exchange; YAML is better for config files. This tool focuses on YAML syntax validation.
What are common YAML errors?
Indentation errors (YAML uses spaces, no tabs), missing space after colon, unquoted strings (with special characters), inconsistent list formatting. This tool detects and highlights specific error locations.
Which YAML features are supported?
Basic key-value pairs, nested objects, arrays, multi-line strings (| and >), anchors and references (& and *), automatic type inference. For complex YAML features, use specialized parsing libraries.
