Online  Tools  for Home Assistant

You can use the online service YAML Validator-https://codebeautify.org/yaml-validator/ to check if your YAML syntax is correct

Paste in your YAML and click "Go" - we'll tell you if it's valid or not, and give you a nice clean UTF-8 version of it. Optimized for Ruby.
