What Highlight YAML does

Highlight YAML is a free online utility that transforms raw YAML code into a color-coded visual representation. By applying distinct colors to structural elements such as keys, values, lists, and indentation levels, the tool enhances readability and helps users quickly identify potential syntax errors or inconsistencies within complex configuration files. The output provides a structured view that makes it easier to inspect the layout and content of YAML data without requiring a full validation pass.
