Terms of use

Last updated 30 October 2026.

FormatYAML.com is provided free of charge, as is, without warranty of any kind. You are responsible for reviewing output before using it, in particular in production configuration.

The semantic check compares YAML representation graphs under the selected profile. “Verified equivalent” means the formatted text parses to the same YAML data as the source; it does not mean an application, template engine or platform will behave identically, and it does not validate Kubernetes, CI or other schemas.

Do not use the site to process data you are not permitted to handle. Because processing is local, the operator never receives your content.

Open-source components are used under their licenses (yaml: ISC, fflate: MIT, Next.js and React: MIT, fonts: SIL Open Font License).
