Frequently asked questions
Questions about YAML Formatter & Validator
Does this tool support YAML comments?
Yes. Formatting an existing YAML document preserves its comments whenever they can be represented by the YAML document model.
Can YAML contain multiple documents?
YAML supports multiple documents separated by three dashes. This first version accepts one YAML document at a time.
Why is YAML indentation important?
YAML uses indentation to represent nested structures. Incorrect spacing may change the meaning of the document or make it invalid.
Are YAML files uploaded?
No. Validation, formatting, conversion and file reading happen entirely inside your browser.
