About JSON to YAML

JSON to YAML turns a JSON value into block YAML with a two-space indent. Objects become key: value lines, arrays become - item lines, and a JSON array at the root stays a top-level sequence. Key order follows the JSON text.

Strings stay plain when they are safe to read back. A string is wrapped in double quotes when it is empty, looks like a number, boolean or null, or contains a character such as :, #, brackets or a line break. Backslashes and quotes inside those strings are escaped.

Conversion runs in your browser as you type. Swap sends the YAML to the JSON side so objects, arrays, strings, numbers, booleans and null can be checked on the way back. Comments are not part of that round trip.

Frequently asked questions

What does JSON to YAML convert?

It parses one JSON value and writes block YAML. Objects, arrays, strings, numbers, booleans and null each get a YAML form. A root array becomes a top-level sequence, and object keys stay in the order they were parsed.

When is a string quoted?

When leaving it plain would change its meaning. Empty strings, strings that look like numbers, booleans or null, and strings that contain characters such as colon, hash, brackets, quotes or a line break are written as double-quoted scalars.

Does a round trip keep comments?

No. The YAML this direction writes has no comments, and the JSON direction does not promise to keep comments that were in YAML you pasted. Values round-trip; comments are dropped.

Is the text I paste uploaded anywhere?

No. Conversion runs in your browser and the text you paste is never uploaded, logged or stored. Google Analytics records page views and feature use, never content.
