Working with YAML Validator

Review configuration text before placing it into a project. YAML indentation and quoting affect structure, so inspect both the error location and nearby lines. A syntax check helps catch malformed input before application-specific validation.

How to use YAML Validator

  1. Paste YAML or open a YAML file.
  2. Review the editor's validation feedback.
  3. Correct indentation or syntax issues and save the revised content.

YAML Validator example

Paste a small mapping with an indented list, then compare how a misplaced indent changes the parser feedback.

What to expect from the result

Valid YAML syntax does not mean the configuration is valid for Kubernetes, CI, or another application. Use that application's schema and validation tools as well.
