Online JSON to YAML converter

Convert your data from JSON to YAML and back and verify their validity.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It is easy to read and write and easy to parse and generate using code.
It is based on a subset of the JavaScript programming language.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization language used for configuration files and data storage or exchange. It uses a minimal syntax that relies on indentation to define the structure of the data.

Differences between JSON and YAML

JSON and YAML are both used to represent data in a structured way but their syntax and features are different:

  • JSON uses braces {} to define objects and square brackets [] to define arrays. YAML uses indentation, colons and dashes to denote key-value pairs and lists.
  • YAML supports comments, while JSON does not. A comment in YAML is indicated by the # character.
  • YAML allows for more flexibility in quoting strings, supporting both single and double quotes as well as literal blocks of text. JSON requires double quotes around keys and string values, and does not support multi-line strings.
