YAML Formatter is an online tool to format, beautify and validate YAML code. Feel free to use it for your YAML files. You can paste your YAML code in the left editor, and it will be automatically formatted in the right editor. You can also copy the formatted code to your clipboard or download it as a file. Both editors support syntax highlighting.
YAML is a human-readable data serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted. It uses Python-style indentation to indicate nesting and does not require quotes around most string values (it also supports JSON style [...] and {...} mixed in the same file). The YAML file extension is usually .yaml or .yml.
