Using this tool

Convert JSON or JSON5 objects into readable YAML configuration.

Actions: Convert

Example

This JSON5 example uses single quotes, unquoted keys and trailing commas; output is YAML with two-space indentation.

Example action and settings

Action: Convert
Indent spaces: 2

Input / action

{name:'Ada', items:[1,2,],}

Result / expected behavior

name: Ada
items:
  - 1
  - 2

Available options: Indent spaces

Scope and limitations

JSON5 comments are not preserved; non-finite numbers and unsafe integers are rejected.

Common mistakes

Accepting JSON5 does not make the output JSON; save the generated result as YAML.
