What is YAML Viewer?

YAML Viewer lets you paste or upload YAML files and instantly see a formatted, syntax-highlighted tree view. It validates your YAML against the spec, highlights errors with line numbers, and lets you collapse or expand nested sections to navigate large config files quickly.

How to use

1. Paste your YAML content or drop a .yml/.yaml file into the editor area.
2. The viewer instantly validates the syntax and highlights any errors with line numbers.
3. Switch between tree view and raw view, collapse nested sections, and download the formatted output.

Result

You have a Kubernetes deployment manifest with 200+ lines. Paste it in to quickly validate all required fields are present, spot indentation errors, and navigate to the container spec section by collapsing other nodes.
