Convert the other way: YAML to JSON

Free to use. Your input stays in this browser.

How to use it

Paste JSON or drop a .json file.
The YAML appears as you type.
Copy it or download it as a .yaml file.

Strings that YAML would read as another type are quoted. "true", "no", "null", "1.0", and "2024-01-05" keep their quotes, so YAML 1.1 and 1.2 parsers both read them as strings.

Text with line breaks uses a literal block (|), and numbers keep their exact digits.

Example
