Valid, readable YAML every time
The YAML Formatter beautifies, validates and minifies YAML documents — the format of CI pipelines, Kubernetes manifests and countless configuration files. Indentation is normalised, validation reports the exact line of any syntax error, and YAML-to-JSON conversion is one click away.
YAML's indentation-based syntax means a single wrong space breaks an entire deployment, and the error messages from parsers rarely point where the mistake is. Validating a manifest before committing it saves a failed pipeline round-trip; formatting it makes nested structure legible to teammates.
Parsing runs locally with a full YAML 1.2 engine in your browser. Paste a pipeline definition, fix the flagged line, format for readability, and copy it back — or convert to JSON when a tool in your chain prefers object notation.
Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
