Frequently asked questions
Is converting JSON to YAML free?
Yes. Conversion is free, with no sign-up and no watermarks.
Are my JSON files uploaded anywhere?
No. The conversion runs in your browser, so your files never leave your device.
What is kept when converting JSON to YAML?
The whole structure and every value: nesting, lists, numbers and booleans. XML attributes become keys prefixed with @, repeated elements become arrays, and codes with leading zeros stay strings. Comments are not carried over.
