YAML Viewer FAQ
What is YAML?
YAML (YAML Ain't Markup Language) is a human-readable data serialization format. It uses indentation to represent hierarchy, making it easy to read and write. YAML is widely used in DevOps, cloud infrastructure, and application configuration.
What is the difference between YAML and JSON?
YAML is a superset of JSON with a more human-friendly syntax. YAML uses indentation instead of braces, supports comments with #, and allows multiline strings. JSON is more compact and widely used in APIs, while YAML excels in configuration files.
Can I view Kubernetes config files?
Yes! Our YAML viewer handles all YAML files including Kubernetes manifests, Helm charts, Docker Compose files, GitHub Actions workflows, GitLab CI pipelines, and any other YAML-based configuration.
Does it validate YAML syntax?
Yes! The viewer automatically validates your YAML syntax on load and highlights any parsing errors with line numbers, helping you quickly identify and fix indentation or formatting issues.
