Example

Note how the version string stays a string, not a number.

{
  "name": "json-utils",
  "version": "1.0.0",
  "private": false,
  "tags": ["json", "tools"],
  "author": { "name": "Ada", "active": true },
  "score": 9.5,
  "notes": null
}

Frequently asked questions

Is JSON to YAML lossless?

Yes. Every JSON value has an exact YAML equivalent, and the converter quotes ambiguous strings so types are preserved.

Can I convert back?

Yes, use the YAML to JSON tool. YAML comments and anchors do not survive a round trip through JSON.
