Frequently asked questions

Is key order preserved?
Yes. The converter keeps the order of keys exactly as they appear in your JSON.
Which YAML version is produced?
YAML 1.2 by default. You can select 1.1 if you need compatibility with older parsers.
Are strings kept as strings?
Yes. Values that look boolean-like or numeric but are strings in your JSON stay quoted so their type is not changed.
