About YAML Beautifier

YAML's readability depends entirely on correct, consistent indentation — a single misaligned space can silently change a value's nesting or break parsing altogether, and these mistakes are notoriously hard to spot by eye. This tool parses your YAML with a real YAML parser and re-serializes it with clean, consistent two-space indentation, catching syntax errors along the way.

Because it uses `js-yaml`, the same battle-tested library many JavaScript and Node.js tools rely on for YAML parsing, it correctly handles YAML's full feature set — nested mappings, sequences, multi-line strings, anchors, and the various scalar styles — rather than a simplified approximation that only works on basic key-value files.

This is useful for cleaning up a YAML config file (Docker Compose, GitHub Actions workflow, Kubernetes manifest) that's been edited inconsistently across a team, validating that a YAML file is actually syntactically correct before deploying it, or just reformatting YAML pasted from somewhere with inconsistent spacing.

How it works

  1. Paste your YAML. Any YAML document — config files, workflows, data.
  2. Parsing and validation run automatically. Syntax errors are flagged clearly.
  3. Copy the reformatted result. Clean, consistent two-space indentation.
