About JSON to YAML Converter

Converts any JSON document into YAML with your choice of indentation.

Integers too large for JavaScript's number type are carried across exactly, so an ID like 12345678901234567890 does not come out rounded - a common and hard-to-spot bug in other converters.

The conversion happens in your browser.

How to use it

  1. 1Type or paste your text, or open a file.
  2. 2Choose any options - the result updates as you type.
  3. 3Copy the result or download it as a file.
