How do I convert JSON to YAML?

Paste your JSON into the left panel and the YAML output appears instantly on the right. You can also upload a .json file using the file upload button. The conversion happens in real-time as you type.

Can I convert YAML back to JSON?

Yes! Click the swap button (↔) to switch to YAML to JSON mode. The tool supports bidirectional conversion — paste YAML on the left and get formatted JSON on the right.

What is the difference between JSON and YAML?

JSON uses braces {} and brackets [] with quoted keys, while YAML uses indentation-based formatting that is more human-readable. YAML supports comments and multi-line strings natively, which JSON does not. Both can represent the same data structures.

Is my data safe when converting?

Yes, all conversion happens entirely in your browser using JavaScript. No data is sent to any server. Your JSON and YAML content never leaves your device.

What indentation should I use for YAML?

The most common YAML indentation is 2 spaces, which is the default in most tools and CI/CD systems like GitHub Actions. 4 spaces is also popular for better readability. Use the indent selector to choose your preference.
