Formatting and validation of YAML documents.

Input data
Result

YAML is a data serialization format often used in configuration files (Docker Compose, CI/CD, Kubernetes). The tool checks the syntax and formats the document with unified indentation.

What happens if the YAML is invalid?

The tool will show an error message with a description of the syntax problem.

Is data processed on the server?

No, parsing and formatting happen entirely locally in the browser.
