Yaml prettifier tool What is a yaml prettifier?
This YAML prettifier rewrites ugly YAML (Yet Another Markup Language) files to beautiful YAML files. It can uncompress compressed YAML and expand inline YAML syntax. It only has one configuration option which defines how many spaces to use per indentation level.

Beautify a minified YAML file
In this example we prettify a YAML file that was compressed earlier. Inline syntax gets expanded and indented with two spaces per data structure depth level.
[{name: 'unshielded twisted pair', speeds: [10mbps, 100mbps]}, {name: 'shielded twisted pair', speeds: [10mbps, 100mbps, 1gbps]}, {name: 'fiber optics', speeds: [100mbps, 1gbps, 10gbps]}]
- name: 'unshielded twisted pair' speeds: - 10mbps - 100mbps - name: 'shielded twisted pair' speeds: - 10mbps - 100mbps - 1gbps - name: 'fiber optics' speeds: - 100mbps - 1gbps - 10gbps
