Frequently asked questions

Does converting change my data?

No. Objects, arrays, strings, numbers, booleans, and null values are carried over to YAML notation as-is, and key order is preserved.

Can any JSON be converted?

Yes. As long as the JSON is valid, the top level can be an object, an array, or a single value. If there's a syntax error, the file is not converted and you'll see a message.

How is indentation handled?

The output uses 2-space indentation in standard YAML style, so the structure stays easy to follow even with deep nesting.

Can I convert back to JSON?

Yes. Use the companion YAML to JSON converter to get the same data back.

Is my data sent anywhere?

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