Question 1

What does the YAML <-> JSON Converter do?

Accepted Answer

It converts YAML to JSON and JSON to YAML instantly, in either direction.

Question 2

Is my config file uploaded anywhere?

Accepted Answer

No — conversion happens entirely in your browser, so you can safely convert Kubernetes manifests, CI configs, or other files that may contain secrets or environment-specific values.

Question 3

Why did comments in my YAML disappear after converting to JSON?

Accepted Answer

JSON has no concept of comments, so any comments in your source YAML are dropped during conversion — this is expected and unavoidable.

Question 4

Does it preserve YAML anchors and aliases?

Accepted Answer

Anchors and aliases are resolved into their full expanded values during conversion, since JSON has no equivalent shorthand for referencing reused values.

Question 5

Is this tool free to use?

Accepted Answer

Yes, it's free with no account required.
