Frequently Asked Questions
What is the difference between JSON and YAML?
They represent the same data structures, but YAML uses indentation and is easier for humans to read and comment, while JSON uses braces and is stricter — better for machine interchange.
Does YAML support comments?
Yes, YAML allows comments with #, whereas standard JSON does not. Comments are dropped when converting YAML to JSON.
Why did my YAML fail to convert?
YAML is indentation-sensitive — mixing tabs and spaces, or inconsistent indentation, is the most common cause of errors. Use spaces consistently.
