YAML Formatter and Validator

Online YAML formatter is a tool that helps you validate, format, and analyze YAML (Ain't Markup Language™) data. It also validates syntax of your data and shows whether it's valid YAML or not. To use this YAML formatter, just paste content to editor and click to format button.

One of the main advantages of YAML is its readability. It is designed to be easy to read and understand, even for those not familiar with programming. It uses indentation to denote nesting, and can be written in any text editor, making it very accessible.

YAML is also very flexible and extensible. It supports multiple data types, including strings, numbers, booleans, dates, and arrays. It also supports complex structures, such as maps and lists, as well as references to other YAML documents. This makes it easy to store and manipulate data in a consistent way. YAML is widely used in many different applications. It is used as a configuration format for many web applications, such as Ruby on Rails, and is also used to store data in JSON databases. It is also used for data serialization in programming languages, such as Python and Java.

YAML is also popular for its use in DevOps and configuration automation. Many DevOps tools use YAML to define the structure of configuration files, and to store data in a consistent and easy-to-read way (such as kubernetes). This makes it easy to define automated processes, such as deploying applications, and to share configuration information between different teams and applications. YAML is also popular for its use in scripting. Many scripting languages, such as Bash and Python, use YAML to define variables and functions, as well as to store data. This makes it easy to manipulate data in a consistent way, and to share scripts across different systems.
