Convert JSON to YAML for configuration files and manifests. Transform API payloads and settings into readable YAML with proper nesting and quoting.
Format, beautify, and validate JSON online. Pretty-print with 2- or 4-space indentation, fix syntax errors, and inspect nested structures instantly.
YAML uses indentation to denote structure (no tabs, only spaces). Standard formatting uses 2-space indent. Keys are sorted alphabetically in strict mode. Multi-line strings use | (literal) or > (folded) block scalars.
Indent: 2 spaces per level; Block sequence: dash + space; Mapping: key + colon + space + valueYAML is a superset of JSON with support for comments (#), anchors (&), aliases (*), and multiple documents (---). It trades verbosity for readability but is sensitive to whitespace errors.

Expand a compact one-line YAML config into readable multi-line block format.
→ Expanded block-style YAML with proper nesting
YAML strictly forbids tab characters for indentation. Always use spaces (2 or 4). Configure your editor to insert spaces when Tab is pressed for .yaml files.
Strings like "yes", "no", "true", "null", "1.0" are interpreted as booleans/nulls/floats in YAML 1.1. Quote them: "yes" or use YAML 1.2 which reduces implicit typing.
Format and beautify YAML with consistent indentation online. Validate structure, fix spacing, and pretty-print configs for CI, Docker, and Kubernetes. It applies the yaml formatting rules (Indent: 2 spaces per level; Block sequence: dash + space; Mapping: key + colon + space + value). For example: format a kubernetes manifest — Clean up a messy deployment.yaml with inconsistent indentation and sort keys for version control.
