Frequently asked questions

Can I convert YAML that contains multiple documents?

No. Multi-document YAML separated by --- is not supported. Split the documents and convert them one at a time.

What happens to comments?

JSON does not support comments, so they are removed from the result. All the data values themselves are preserved.

How are anchors and aliases handled?

Values defined with anchors (&) and referenced with aliases (*) are expanded into their actual values. No reference syntax remains in the resulting JSON.

What does the resulting JSON look like?

It's saved as readable, indented JSON. Key order is kept exactly as in the original YAML.

Is my data sent anywhere?

No. Your files never leave your device. Conversion runs inside your browser and nothing is uploaded.
