How it works

Complete the job in three clear steps

Add JSON or YAML configuration data to the private browser workspace.
Choose the available settings and create the equivalent JSON or YAML document.
Review the result, then copy or download it before leaving the page.

Important

Check the result before relying on it

Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.

Practical details

What this Lucaden tool does

This two-way converter uses js-yaml's safe loader and dumper for configuration files, deployment manifests, and structured notes. Conversion preserves arrays, objects, booleans, numbers, strings, and null values while formatting the output for review.

Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.

Questions

About this tool

Can YAML comments be preserved?

No. Comments are not part of the parsed data model, so they cannot survive a round trip through JSON.

Does the tool execute YAML tags?

No. It uses the safe supported schema and does not execute arbitrary code.
