How do I format code on this page?
Paste code into the left editor or load a file, choose the options you need, and select Format. Review the result on the right, then copy or save it.
YAML Formatter is a tool designed to format and beautify YAML code, making it more readable and easier to understand. It automatically adjusts indentation, aligns data structures, and cleans up unnecessary clutter in the code. This tool is especially useful for developers and system administrators who work with YAML files extensively. YAML Formatter helps in maintaining and debugging configurations and scripts, providing a clear structure that adheres to best practices.
Paste code into the left editor or load a file, choose the options you need, and select Format. Review the result on the right, then copy or save it.
The input must match the selected language or syntax. Check incomplete statements, unmatched brackets or quotes, and a dialect or mode that does not match the input, then format again.
A code formatter reads language-aware tokens and nested structures, then rewrites indentation, spacing, and line breaks according to a consistent rule set. It does not compile or run the program, so formatting is not a correctness or security check.
Use spaces rather than tabs; 2 spaces per nesting level is the most common YAML convention. Keep deeper indentation only when the existing file already follows it consistently. YAML Formatter intentionally keeps the controls simple: enter valid YAML and select Format. The Language menu only navigates to another formatter.
