Frequently Asked Questions
Can it convert YAML back to JSON?+
Not yet. This tool converts JSON → YAML only.
Why are some strings in quotes?+
Values like "true", "123" or text with colons would change meaning in YAML, so they are quoted to stay strings.
Is my data safe?+
Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
