When to use this YAML beautifier
Use this YAML beautifier for configuration snippets, CI examples, deployment settings, and documentation blocks where indentation needs to be easier to inspect. YAML is sensitive to spacing, so readable indentation is important before validation or conversion. The goal is not only to make the content look cleaner, but to make parent blocks, nested values, and repeated sections easier to inspect before you save or share the result.
Beautifying content is especially helpful before running a comparison. When indentation and line breaks are consistent, real changes are easier to find and formatting noise is less distracting.
