Question 1

Is my data uploaded to a server?

Accepted Answer

No. The conversion runs entirely in your browser using JavaScript. Your JSON never leaves your device.

Question 2

What's the difference between JSON and YAML?

Accepted Answer

JSON and YAML both represent structured data. YAML is more human-readable and commonly used for configuration files (like Docker Compose or Kubernetes manifests), while JSON is more common in APIs and is stricter about syntax.

Question 3

Does this handle nested objects and arrays?

Accepted Answer

Yes, any valid JSON — including deeply nested objects and arrays — converts correctly to its YAML equivalent.
