A quick guide
Choosing the right YAML tools
YAML uses indentation to describe structure, so a small spacing change can affect how a configuration is read. Use the validator to locate syntax problems, the formatter to improve readability, or a converter when another application needs JSON. Review the output before replacing a working configuration.
