Frequently Asked Questions

Does conversion change the data?

No. The converter preserves all values, types, and nesting. The only change is the syntax format. Note that YAML supports some types (like dates) that have no direct JSON equivalent — these are converted to strings.

Can I convert minified JSON?

Yes. The converter accepts both formatted and minified JSON as input. The YAML output is always formatted with 2-space indentation.

Does my data leave the browser?

No. Conversion runs entirely in your browser using JavaScript. Your data is never sent to any server.
