  • As soon as the editor detects a valid YAML, it displays the result.
  • In order to download the results you must click on "Download" button.
  • You can also copy the result to the clipboard by clicking on the button "Copy to clipboard".

To convert JSON data: It's analogous to the YAML conversion.

About YAML

YAML Ain't Markup Language (YAML) is a human-readable data serialization language. This format is useful for configuration files. It can also be used in many applications for other use cases.

YAML has a minimal syntax and it is often more readable than XML. It is useful in case of configuration file.

YAML natively encodes scalars (string, int, ...), and also array.

Many programming languages include code to read and write YAML data (C/C++, Python, Java, PHP, JavaScript, ...).
