YAML Validator is a free online developer tool to validate YAML data against the YAML specification as known as YAML linter instantly.
You can either browse a YAML file locally from your device or enter it manually.
Once you've entered YAML, click the validate button to check if the input YAML is valid. If so, the success message will be displayed accordingly.
Otherwise, the errors including line numbers and excerpt code will be printed so that you can get them fixed easily.
